Mass Effect 2 & Final Fantasy 13

I'm about t0 get my last 2 achievements in Mass Effect, but I been procrastinating cuz I don't wanna miss those damn hidden items in the DLC overlord...  On top of that any one got a suggestion on how 2 get the Treasure hunter achievement in FF 13 easily? It's the only one I'm missin n it seems like it'll take another 50 freakin hrs 2 get, 50 hrs I'm not willing to devote to item collecting!  Dammit help meeeeee!!!!
