Default [Q] Help with custom rom?

Okay, so ICS is great, and I love it but I really want everything to work. I am getting into developing, and have been learning a lot. I want to make a custom gingerbread rom, and I am on 906. Currently just deodexed and rooted. I want to use this as my base for the rom. I flashed the deodexed rom to my phone because I accidently flashed MAVRom on the non-safe partition (had CWM instead of Safestrap). How would I get the .zip to customize it? The deodexed "rom" is here but if you aren't using 906 already whats the point, because the system isn't in it, just app and framework. What would be the easiest, or best, way to get this on the road?
