[...] could use a new mouse also[...]
get a "Logitech VX Nano" - costs a bit more, but works so great, worth every penny. I'm a programmer, using the PC at least 10h/day and all my mouse are VX Nano by now.

Have fun - the new office can be a nightmare when beginning, but as you figure out how to modify the new menubar, it's a real pleasure. Win7 is great - I love to throw the windows around, attaching them to the sides and stuff like that. Win7 is definitely a plus!
