I know this thread is over a month old but you can always download the cab file that Pegasus did for someone else, unzip it to a folder on your machine and then dig through the files that he's modified.
Like bignadad said on a previous page, a lot of this is/has been trial and error by a lot of people so you won't be the only one. I'm in the process of putting together a spreadsheet of as many of the 1251 manila files on my stock Verizon TP2 WWE. I'm using a combination of posts, the m9editor, manila editor and cfg gui (along with converting them all to png files, modifying the ones that convert, uploading and seeing what they change) because not all of them have "friendly names". I don't think the friendly name is embedded anywhere in the file and instead comes from the DLL or an ini file (wouldn't that be nice?)
Hopefully when I'm done I'll have graphic file sizes along with how large the actual picture should be inside of each file (not always the same thing).
I've learned a SHLOAD over just the last week by downloading things like Spike's Micneo taskbar (with MightyMike CDMA fix) and a couple of cab files that modified the look of the "Settings" and "Communications" screens. I've then taken it farther to modify the "Customize Tabs" screen to match my new custom slider. All from disassembling other peoples cab files, looking at the xml document and figuring out what manila files and/or .dlls got modified.
HTH,

Phone: Verizon Touch Pro 2 - WWE
ROM: Stock (Work bought it so 'no touchy the monkey!')
Tweaks: Various and sundry but mostly visual enhancements with a couple of noteable exceptions.
1) MightyMike's 1% Battery Fix for Verizon
2) No push Internet
3) Opera goes bye-bye when I close it
4) Spike's MicNeo Taskbar (Variant 3 with MightyMike's CDMA fix)
PS - Yes I plan on posting it all when I'm done.
I might even post my 'uber Windows 7 package'...not that there aren't enough of those already.
