That should cover you, its got most codecs in there.

I don't understand what your asking about the programs, but to get any program off your 'puter just un-install it. Just go to your control panel, then add/remove programs, and uninstall from the list. If it ain't in the list, find the folder in "programs" in your c: drive and just delete the folder if there isn't an uninstall.exe file in it.
