Hi Guys
So I guess I never came back and gave an update after I got the laptop, so long story short I am posting this with it. Its a Mid 2009 15" Macbook Pro 2.56 C2D
When I got it, it turned out to not be in that bad shape as I thought. It would power on and I could run it on an external display I could even see the screen working with a flash light, so I opened it up and could see where the coffee had gotten in to it I cleaned that with hight % rubbing alcohol took the screen cable loose and could see burnt pins on the cable and the socket. I can only assume the the back light inverter shorted out when the coffee was spilt. I looked around online and found a company on ebay that could replace surface mount components on the logic board and the backlight inverter for $259, so 2 weeks later I had a good as new 2 year old $1700 laptop for right at $500, and I love the thing. I dont think I could go back to a 13" screen now.
I also did some testing and it looks like the Glass track pads and unibody keyboards are USB but I could not find any solder points on them, however the link that you posted with the 4 solder points do work on the white MB keyboard and track pads I have one of those to that I picked up for $30 on ebay.
