ASUS P5N7A-VM Fine tuning

[cabal2000]

Modded 504 firmware
8 gigs of ram
Fire-wire Card (PCI)
Snow Leopard 10.6.1

I am a very noobs on this subject but learning.
-Can I move the operating system from my 300 gig to my 1 tb drive?
-when I go the About this MAC it does not show the Quad core 2.83GHz Q9950 processor.
-IS there a fire-wire kext for SN64bit? I just installed it and do i get an error when I boot. I have to get around it with a Boot-cd.
-I have a Microsoft wireless keyboard and mouse. The Keyboard is PS2 and the mouse is USB. I can't plug in the keyboard ps2 connection. It still works without it but would love to have it working.
-I can shutdown the system but I can't reboot. I have to turn the power off, wait and power up again.

Any Help would be great!!!
