snowleo and win7

alrighty. i am new to here, but im not a novice. ik all the terms and everything, and a computer inside and out.

last night i got snowleo's version of snow leopard to work on my laptop. with a few problems of course:

1: the touchpad didnt work
2: the keyboard didnt work
3: since i had made it a guid partition table, windows wouldnt install.

so my questions are: how do i get those to peices of hardware to work, and can this version of snow leopard run on an MBR partition table? i need at least something with the tochpad and keyboard working so i had to wipe it and put windows on. i need some hlep here please!
thnks in advance!
