Firstly how do i drag icons to the taskbar thing..it doesnt let me do it even after unlocking the taskbar, and i had to install xp32 because vista wasnt working but i didnt take vista off properly..how do i do this?
1: Taskbar thing??? Do you mean the quick launch icons? You normally can just drag icons there even if it's locked, maybe they are just hidden (there should be a small "+" sign or something like that to click.

2: You can't install XP if vista is still installed (well you can but it's a pain in the ass). So if you managed to do it, you probably did it right
