Jerseyboy, I have a few questions about what you've bought ... and a few hopefully gentle comments on some of them.
1) Why you are spending bunches of money on 2" filters when none of your current eyepieces need them?
2) Why you are buying any filters at all right now? I'd personally wait a while until you figure out what you'll need.
Color filters are rarely useful when you are starting off. Color filters enhance very subtle planetary details that take a while for your eyes to be trained to see. They are however fun to try and they do teach you some things. Planetary viewing is done at higher magnifications, where you are not likely to use 2" eyepieces.
The Neob filter is very very subtle in it's visual effect. It's useful on lunar features and while light solar work. The variable polarizer is useful on very bright (low power) lunar views. It is does however take some fiddling to use effectively. You must rotate one filter with respect to the other to fine tune the amount of polarizing effect ... it's not very easy to rotate one filter when it's on the end of an eyepiece buried in your diagonal. The way most folks get around this is to attach one of the filters to the input side of the diagonal, and then other to the eyepiece. Then you rotate the eyepiece to tune the polarizing effect. You won't be able to easily do this with an SCT 2" diagonal (there's no 2" filter threads on the diagonal itself) ... but it would work if you had a 1.25" filters and used your 1.25" diagonal.
The OIII effect is not so subtle on very specific objects but you are dealing with already very limited viewing. Planetary and some reflection nebulae are great fun and the OIII certainly allows them to stand out more (no filter enhances (makes brighter) an object or details, it just changes the contrast against the background or other features of the object). The OIII is not a general purpose filter, it's not going to be particularly useful on most emission nebulae and galaxies, or on stellar objects (open or globular clusters). This means it probably won't be something you'll be regularly using, more of a targeted or special occasion type of thing ... but right now might be one of those "special" occasions, there are some nice objects high in our skies right now that will benefit from the OIII filter.
The bottom line though is that none of the filters are likely to show you things that you couldn't see without them, they will just make the views a little bit better ... in some cases a very little bit. With experience though you'll likely find that once your eyes are well trained that with a filter or two you'll be able to pick out details or objects that are on the limit of your visibility.
Your Orion afocal camera mount can handle an eyepiece with a maximum diameter of 45mm, so I don't think the zoom will fit (close though so maybe it will). The included Celestron eyepieces will be just fine.
You are "featuring up" even before you get your first scope. That's a recipe for spending more money than you initially need to. All the things you've bought are good quality, and none are bad purchases but with some experience you may find that you won't want or need some of them.
