It will be six inches larger than whatever you build...
Incidentally, i'm looking at around 15'x28'x9' right now, and could go possibly wider/thinner, but not much longer.
That's plenty of depth, I would recommend wider. It depends on how many seats you want, too - but if I did it over again my room would have been a foot wider and 2 feet deeper. It's 16x22 now, 17x24 would have been better for me. 10' ceiling.
Also, i have the option to drop the floor in my theater area another foot from 9ft to 10ft. Is this worth doing for the extra cost, or is it just a "nice" thing to have taller ceilings? (i've seen great builds in here go even deeper..) If so, should I drop the entire theater area? or just some portion of it for the intended first row seating?
Helps a lot for fitting in two risers and having headroom to hang the projector, and also to give the room a more theater-like feel. But drop the entire area, not just a section, as you'll inevitably make it too big or too small - and doing so also means you've set the use of the room in, well, concrete. If you or a future owner want to use the space differently, it'll be a challenge.
And for the bonus question... should I even worry about theater electrical or hvac now while I build the rest of my home? or am I fine to worry about all this later when i actually design the theater? and just get the "shell" in place now?
Yes, get the HVAC and electrical sized and dropped to support the theater. I had two 20A circuits dropped into the unfinished area during construction for future use. HVAC planning was done somewhat to add a zoned system to support it - but my conversations with the HVAC guys should have been more detailed... Turned out ok, but I had told them explicitly that there was going to be seating for 12-15, and I have 30-40 people in the game room area for poker tournaments, the load calculations might have been a bit different!

Talk with your HVAC guy, but the important point is that with a large number of people in a nice, sealed up theater with an equipment stack and projector, you will likely need cooling even in the winter. Make sure your system can do that.
2. if a 200amp service to my house is good, or if i need to plan for an extra sub-panel put in now next to the theater for speakers/amps etc..
If there's a place you can put a sub-panel, it's a great idea. Otherwise 2-3 circuits placed so they can be used anywhere in the theater / equipment area is probably enough. But do get those things staged now.
When i do move forward with the build, i'll probably be asking the erskine group to help with the plans..
Yes, do that, at least the Theater Layout Service, and you'll need to check with BIG to see if he likes to ski...
