both are overkill expansive, I'd get the ram since you won't need to replace that one and you will replace the SSD in two years with a 512GB one that will be 200 bucks
 
im running osx 10.6.4 , itunes , chrome with 3/4 open windows comfortably on 1gb ram right now, only at 73% used.

ssd is more beneficial then ram.
