Hello and welcome to the forum.
The upgrade section is only for posting releases of roms or kitchens so this will most likely be moved to the regular tp2 section. secondly there are a couple of stickied posts already that essentailly do exactly what you are attempting, they are linked below.
TP2 Cleanup
Tweaks, Hacks, Tips, Mods
Those two post should be a good start and keep you busy if you want to avoid flashing. good luck!
