I found with some of the functions in Compiz require a system restart and then what changes you made will show up. I have never had Compiz ask for a restart after a feature change which it should.
I have it working perfectly on Linux Mint 12 after I figured this out. Hope this helps.
Also, if you don't have any luck, try Cairo Dock. It does pretty much the same stuff as Compiz and is a little easier to figure out.
