All my files are fairly small. I've taken off photos, and starting installing my games on the G drive and uninstalling them from the C once I've made sure they run on G. Pretty much all that's left is things that I have no idea of what they are, hence the need to ask.
I think I need more information on how to do the things on your list. I have Windows XP, Service Pack 3. Should this conversation be moved to the Windows section of the forum?
Adding: Wow, I disabled Hibernation and it did make a significant difference.
