Another Idea is to make your own folders.
I didn't want iphoto, photobooth, microsoft messenger data, and other things with my files, so I left them in their default directories.
I created a folder called "Files" and inside that are:
"Photos"
"Documents"
"Apps" -- this is just a folder with Aliases to the apps I use often, and aren't in the dock.
I drag each one to the finder side bar, and drag the old ones out so that they vanish in a puff of smoke. Now you may think it looks ugly with the Generic folder icons on them, rather than the old ones, but there is a solution.
