Truthfully, just a barlow will allow a lot of different magnifications with the 25mm you got with the scope. ~12.5mm if inserted after the diagonal, and ~8mm if placed between the scope and the diagonal. To go along with that, maybe a 32mm plossl to get the widest possible FOV at low power.

If you're looking to get some inexpensive EPs that you may want to replace later, the Agena Astro Enhanced Wide Angle set is a great bargain. You can get the whole set for $135, or buy them individually for about $40 each:
If you want to spend more and move up the food chain to some really good quality EPs, the Baader Hyperions are about $120 and are a great bang for the buck. Since these are more expensive, these would be good to look at if you want to maybe buy one at a time and build up your set over time.
Since your scope comes with a 25mm EP, something in the 13-15mm range would be a good first addition. This would give you more magnification for use with planets or other small targets. My 13mm Hyperion is probably my most used EP.

I would go along with Dan in that something in the 13mm to15 mm is a good start. A x2 Barlow used with the supplied 25mm would give you x12mm If you remove the bottom element from the Barlow and screw it into your 25mm, as you would a filter, it will give you x 1and a 1/2 (17mm). Both focal lengths are approx.
I'm sure you will enjoy the 6se. It is a good scope.

Id just buy an inexpensive 8 to 24 mm Zoom (and I do NOT like zooms) But for your purposes one would be a good idea.. Meade Zhumell and Celestron all sell for well under $100 and all are "acceptable" The Baader Hyperion Zoom is excellent but its over $200.00
The cons are that the FOV is not as great as a single eyepieces BUT who cares it will allow you to see what magnification(s) you seem to be using night after night...

Add my vote to Bob's. A zoom is a handy EP and a good way to explore the range of useful magnification. I own two at the moment (included with used scope buys), an older Vixen and the current and much less expensive $59 Celestron. In head to head comparisons with the Televue zoom on a NS 8 and C5, the Celestron gives up surprisingly little to the more expensive EPs. If this was CR it would get a best buy rating.

My most often used EP is a Meade 5000 SWA 20mm. A 10mm EP is the next choice for me and my sky.

A nice Plossl should do the job, and if you want to spend a bit more, you can get a Televue 32mm for around $120. Otherwise there are many good options below $100 as well.
Your minimum should be around 8mm, practically speaking. Anything below that most likely won't get used often due to seeing limitations.
Thus, a good starter shopping list for your scope would include:
17mm widefield (68o Hyperion or similar)
13mm widefiled (68o Hyperion or similar)
If you add a barlow it will also give you around 8mm and 6mm, for those good seeing nights.
Although I call this a "starter" list, you probably won't need to add many more to cover a good range of magnifications and fields. You'll see users with long lists of EP's, but that's mostly because people like to collect those little shinny things.
In terms of priority, I'd get the 32 first and then the 13. The 17 can be added later to fill the gap.

I own the Baader Mark III zoom, arguably the best of them, and yet I'm not a big fan. They have their place, and for me that place is in my grab and go bag. A zoom obviously replaces several eyepieces so it is handy if you have little space or just don't want to fiddle with a case full of EPs.
But for me, an eyepiece with a field of view of around 68° or more is a big part of the enjoyment of the experience. When I look through EPs with smaller fields I feel constrained - like I'm looking through a straw. And since I often spend time scanning around looking for objects, it feels a bit like I'm trying to find my car keys in my house ... while looking through a straw! I'm just itchin' for more view.
While the zooms have nice 68° field of view at the high mag end, when you start moving the zoom towards the low mag end, the field starts to narrow until it reaches about 50° at the end. And of course, the low mag end is really where you WANT the wide field of view for seeing larger objects or scanning around. For magnification it is a 3x zoom, but for field of view it is only about a 2x zoom. In other words, you only see twice as much of the sky at the low end vs. the high end.
I know many people love the zooms. But I find that whenever I have a choice, I always reach for my fixed focus EPs. The only time I really use the Baader zoom is when I want to take a quick peek through one of my smaller scopes. I store it in a small grab and go bag that I strap around my waist so I can take everything I need out with me in one trip. It's definitely handy in that situation.
Just my 2 cents!

But a INEXPENSIVE zoom just fits the bill for his situation...
I do own a Celestron Zoom that I use with my 4 inch refractor that I use for our clubs outreach sessions and it works very well ..

A very warm welcome to CN and to this forum !
A 6mm EP is far too powerful for a 6SE and even for an 8SE in my opinion !
It's only use is, arguably, in providing an image with ideal Airy rings when collimating. I therefore would have thought that a 10mm was probably the shortest useful focal length EP, for observing purposes, a 6SE could usefully tolerate on a night to night basis.

If I remember correctly ,35mm gives the biggest FOV for 1.25" focusers in most any scope;and my 32mm gets less use than my Celestron 25 or Meade 26.
You will find something close to 15mm and also 10mm useful .
At the right price the Celestron or other kits is fine even if you don't use the smallest EPs but rarely,just because the price individually can be much higher.

I agree that a 2X Barlow is a must since it effectively gives you two magnification options for each EP. I also suggest a 32mm (or 40mm) EP for wider angle views of star clusters and asterisms. And for just "huntin' around for stuff", the 24-8mm zoom can't be beat.
