The very best XIM, Mech, Mouse Combo?

[Quark]

Hello people of Geekus Hackus,

I have finally got one of these on the way to Australia for my 360 - http://xim3.com/shop

So now I really need a good gaming keyboard for use with it and a good mouse.

I play FPS games primarily.

Do any of you people rock out the XIM, and if you do which keyboards and mice have you found to be the best for use with the XIM?

I have read some can be a bit of a hassle to get working with it.

Cheers for the help.
