MacBook 3 1 - late 2007 - 10.5.8 with 2gigs ram 2.2GHz intel core duo

So I was downloading a copy of snow leopard 10a432 and tried moving it to a 8gig usb drive

The download contained:

iousbfamily378.4.3.dmg
kernel debug kit snow leopard 10a432.dmg
SL10A432.md5
snowleopard 10a432 userdvd.dmg

I went for the first thing on the list and installed iousbfamily. Macbook restarted with no functions for onboard keyboard, onboard mouse, and usb ports . Hasn't worked since.

Bottom line , I have performed zap pram and smc reset to no avail! I'm stuck in the sand and I need a life line here. Please and Thank you .
