Are these eyepieces any good? I will be using a CPC 1100. Are they parfocal?

They are ordinary to average, you do get what you pay for with EPs. No chance they are parafocal...(thats not so very important)

They are decent eps and the advantage to this kit is that, for a relatively low cost, it allow you to do a lot of experimentation to discover what you really want and need. You also get a very nice selection of filters thrown in and a terrific carrying case. I think it is a great starter set. I have one, and I am happy that I started with it.
What I learned is that I use the 15mm and the 9mm the most, since I do planetary from my light polluted driveway. The 32mm frames the entire Moon. As a result, I purchased a Televue 9 & 15. Later I will add a 24mm Pan.

Darwin:
With the CPC 1100, you have a very high quality scope. These eyepieces won't come near to doing it justice.
However, as Winnie says, it's not a bad strategy to buy a set like this to experiment with what focal lengths you like etc. Then you can buy good quality eyepieces as money allows.
If you'd rather go for good quality eyepieces right now, I'd recommend one or two of the Baader Hyperions and build on that as money allows. The Hyperions have a 68 degree apparent filed of view, are parfocal, have a comfortable 20mm relief, and are very reasonably priced at about $120 each. Of course, if money is no object, the Televues and other higher priced EPs will certainly provide better views. But in my opinion, not enough better to justify the extra cost.

I agree with Dan, the Baader Hyperions are supposed to be a great value for the money. However, if you are on a budget, I would like to mention that the next step up from the Celestron (GSO) Plossls would be the Celestron X-Cel ED eyepieces. They ARE parfocal and give 20mm of eye relief. They are under $60 each.
You got a 40mm with that scope, which gives you 70x. So get some that will give you around 150x and 250x.
You might want to hang out on the Eyepiece forum for a while. That is really where this discussion belongs.

I do NOT know of ANY series of Eyepieces by ANY manufacturer that are TRULY para focal... many claim to be but most are "only" pretty darn close ...you still have to grab the focus knob and turn a hair or two...even with the best of them...
Like Snogum said...it not important...

You can find the celestron plossls on ebay for very reasonable prices.. I think I purchased a 32mm plossl for 25.00 plus like 3.50 shipping to test with my NS11 when I first purchased the scopes. I purchased a couple of others in the line to get me by for awhile. Eventually you will want to upgrade your eyepieces to get the most out of that scope. I think the celestron axioms and William optics UWAN lines give you the closest thing to a Nagler at half the price. There are several very good reviews on the UWANs here on CN.

The C11 makes many eye pieces shine, it takes a true dog to perform poorly in this scope. So, it would be an economical way to have a decent kit. Over time, with your experience with that set and hopefully test driving other eye pieces, you can add to and improve your selection.
In the mean time you get to enjoy!

I ordered my telescope and it should arrive TOMORROW. I just hope that UPS doesn't beat it up. I wenr ahead and ordered the kit. It includes a barlow and moon filter, which I was going to buy anyway. I'll upgrade the eyepieces later.
I told my wife that I will probably get more use out of this scope in one night than I have out of all of my other scopes put together ever. That may be a bit of a stretch, but it sure will be nice to be able to spend my time looking AT stuff instead of looking FOR stuff and to have the scope actually track stuff.
Two things I want to try is making time lapse animations of Jupiter and observe the ISS - I have software to track it.
Thanks for the advice.

I think the kit is a good purchase.
You get to learn about eye relief, coating qualities, fov and other eyepiece characteristics without breaking the bank.
You get to learn about what lower quality means to you compared to TV, Pentax or others.
You get a set of eyepieces that you don't have to worry about with kids or neighbours using them.
You get to find out about light transmission and what an advantage minimal glass can be under some conditions.
All for $100 or so, IMHO not a bad investment in education.

Frankly, I'm glad that you decided to get the kit. Please, do let us know what you think of it.

So what you are saying, in the kindest way possible, is that it's money well spent because it will teach me that cheap eyepieces are .... well, cheap. 
Sir, you vastly over estimate my ability to discern quality. I'm tone deaf and if such a thing were possible with vision, I'd have that,too.
All kidding aside, it comes with a moon filter and barlow which I was going to buy any way. It looks like I paid $5 - $10 apiece for the eyepieces - they are surely worhh mjore than THAT. I'll upgrade them as I go along. Moving up from 6" reflectors and a 10" that I made the mirror for, all dobs, the leap I will see with this scope cannot be overestimated.
Thanks for the advice, eveyone. I'll give a report of it ever clears up. (I got the scope yesterday).

The individual Eyepieces in the Kit are NOT CHEAP... actually very serviceable the only problem is that the lower mm ones are way too strong to use with a CPC1100 ..which is ok...you can use them in other scopes ...
Put it this way....I someone offered to sell me a Nagler 3-4 mm eyepiece or a Pentax XW 3-4 mm eyepiece for 99 CENTS or the Clestron Kit for 99 DOLLARS...the Kit would be the better buy... at least I could actually use some of its contents in a CPC1100...the high powered High End EP's would be of no use ....

Well not really. It's more about the ability to discern the differences, and not as much about what someone has paid for an eyepiece or any astro accessory.
It has been said a number of times on this thread that you will indeed find the Plossl eyepieces in this kit very usable. In the lower mm range you'll start to discover just how much or how little eye relief you can put up with (a very subjective thing, something everyone has their own opinions on).
My last comment in my earlier post is actually an endorsement for the simple Plossl design rather than a knock. For instance there are times when I find that the Celestron 9mm Plossl will show some subtler low contrast details on the planets compared to a BO/TMB 9mm planetary eyepiece. The BO/TMB is however a much more comfortable eyepiece to use for extended periods of time and that generally means I can see more with it over the course of an evening (patiently waiting for those rare moments of good seeing).
I really do believe that the kit is money well spent, I think you'll probably get a lot of positive use from it.

I use my plossls with my Coronado PST solar scope and they perform very nicely... espically the 9mm. The 15mm and up will be very useful with the SCT and you will find the filters useful. These eyepieces perform very nicely and you will get much joy out of them. The first time I put one of these plossl's in a inexpensive small refractor I was blown away at how much they improved the performance of cheap scope. Made a department store scope actually useful.
