What programs do i NEED for MMS..??

-Today Plugins = Device.
-Anything that's going to run in background or needs to read resources when the device wakes up = Device.
-Anything with hardcoded paths in the program itself which looks in Program Files = Device. Because of this one, it makes things pretty much trial and error.

Everything else should be ok on storage card.

TCPMP should be ok installed to storage card I think. Might just be an issue of editing the shortcut or creating a new one.
HTC Home, Device.
HTC Home Customizer, Storage.
For your camera problem, it may have replaced the shortcuts and then removed them when you uninstalled. Create new shortcuts to \Windows\Camera.exe in \Windows\Start Menu\Programs and \Windows\AppButtons. I doubt it overwrote the original camera.exe.

the titan has plenty of system memory so i just install everything there.
not sure why you want to keep stuff on the storage card... save that space for maps and mp3s and videos etc.
i also keep a copy of all my .cabs there so i have a backup.

if for some reason your card fails or is removed you won't be able to run any of those apps untill you reinstall.

ram use does not change either way if thats what you are concerned about.

i just figured by having less items installed on memory space, and on storage space instead, my phone would move a little bit faster, unless im wrong..
