One thing - I suggest you buy the 60gb if you aren't already. NXE lets you improve your experience in games, especially games like Mass Effect which aren't optimized like they should.
My suggestion is this:
Tales of Vesperia, Last Remnant/Lost Odyssey (whichever strikes you as better)
All 4 WRPGS are excellent, I couldn't pick just one myself. But when in doubt get the cheapest game! 
For your other I suggest instead to get: Braid, Castle Crashers (If you play on getting Live Gold) Geometry wars and a couple of other Live games.
Tease.
