ROM Flashing anxiety (dont kill me)

[lilbitz_1018]

Hi guys, first of all heres a free THANK YOU button.::THANK YOU:: lol click it as a thanks from me. You guys are awesome at responding as best as possible.

I've been lurking around for a little now and done some reading and learning (without trying) from other people's mistakes. I've gone down the line of WM phones and now own a TP (out of toilet paper tho -_-).
I've also done some cab downloading and registry tweaks and I'm satisfied with my phone but somehow, surprisingly I havent flashed a ROM and I'm addicted to hearing about it!
I really want to try it and I'm good with the instructions provided, however I'm realllyyy anxious so I'd like for someone to tell me straight up which ROM could provide a few things I'd like. (if at all possible).

I've already flashed to the Telus Radio to see if my battery life would change. (small change).
Which custom ROM would be best to.
1. Keep most of the useful apps the Sprint TP came with.
2. Keep GPS and Weather updates and all other connections working (no data timeouts).
3. Not loaded with ALOT of games (I'd like battery life-teeter's fine)
4. Useful registry tweaks
5. Updated Opera Build.
6. TF3D working fine (dont really care too much for 6.5)
7. Least complains and bugs (atleast less than stock does)
8. Something that I dont have to constantly be searching for updates.

I hope thats not too much. Overall, what I'm searching for is a custom ROM that has most of the Stock stuff but included registry tweaks and programs that can make it run smoother and have a good improvement on overheating and battery life.

THANK YOU SOO MUCH IN ADVANCE.
