That's not a bad board, but I would check into the bloodrage instead.
Newegg.com - Foxconn BloodRage GTI LGA 1366 Intel X58 ATX Intel Motherboard - Intel Motherboards
It's cheaper, has the same options the Asus does, and seems to be fairly popular. I hear it's name thrown around a lot on other forums.

Also, the motherboard is shown as being in stock here.
Newegg.com - ASRock X58 Deluxe LGA 1366 Intel X58 ATX Intel Motherboard - Intel Motherboards

EDIT:
As far as the mice you've picked out, I've never used any of them, so I can't really offer any help.
