Since I was the OP, I thought I should share: I upgraded my late 08' Alum 2.0 with 4 GB and a 500GB 7200 RPM WD 'Black' HD and its running no prob.
I really don't see a speed boost from SL, but it seems to handle processes and RAM management / release a bit better. If anyone is going to upgrade their RAM, definitely get 8 GB, as ML uses quite a bit more to run than SL; plus the discrete GPU shares 256 MB with the main RAM.
