I just have this D-Link mouse pad with the gel hand rest that my mom got at Big Lots lol. As for a mouse, I have an optical one that doesn't function, so I'm using a 2 button ball mouse.
i have an excellent optical mouse (thermaltake xaser) on a grey generic mousepad. I plan to get a better pad sometime, maybe with a built in gel wrist pad.
I use the Logitch Marble Mouse and nothing else. Well, cept for the remote for the HTPC...
And I have a LavaLamp Mousepad, not sure on the real name, but I got it from Thinkgeek a few years back.
