First, you are very welcome. I saw probably all the same info you saw, which was less than the info you really *need* to figure it out.
The game runs flawlessly on the 60GB, I think. You *might* be able to get it to work with the PS3 Eye, not 100% sure, since I have the 80GB MGS4 PS3. MAN that's a lot of alphanumerics.
I saw some conflicting info on the Kinetic-PS3 Eye setup, but I can state definitively that my 80GB PS3 does NOT allow Kinetic to pick up the PS3 Eye and that it *had* to use the old Eye Toy.
Good luck!
