Question about any ROM's w/ M2D/TouchFLO in it?

[djdafreund]

So everything should be ok as long as i am reasonable with how big the ROM is, which what is the size it shouldn't go past? And also gets confusing since a lot of ROM's are out there, and some mention you still have to install the proper 'Radio' to work with the carrier. That part is kind of confusing also. Thanks a bunch for assisting me with this, it's definitely helping and VERY much appreciated.

Like for example, the ONLY things i guess i would really want to have inside the ROM, versus separately installed would be -
1 Enchasements.OUTLOOK.and.PICTURE
2 AudioManager (Maybe, but either way)
3 Album_2_5_18202622_0
4 YouTubeQVGA 1_5_1820_3327.and.mHubVO (Also Maybe, could be separate)
5 FSP, DShow, WMP, YouTube, Video Fixes
6 my manila fix (M2D most recent build supposedly)
7 Opera_v9.5_build_15233_QVGA (FREAKIN LOVE THIS VERSION!!!)
8 PocketCM_Keyboard

And anything else i could always install to system memory or external memory.
