8GB definitely isn't worth it. 64GB all the way.
Borderlands 2 is alright. Depends on your perspective. If you hold it to the standard of other handheld games, it's actually a really impressive feat. If you hold it to the standard of home console games, it's easily the worst version.
Vita isn't fragile, but I'd strongly recommend getting a case anyway.
And ABSOLUTELY buy a screen protector. Cannot stress that enough.
Vita isn't region locked. I've never imported so many games as I have with Vita. You'll want to bookmark Play-Asia and Videogameplus ;)
Recommendations? Based on what you already said, you seem to like Japanese stuff - so DanganRonpa 1 & 2; Atelier Totori Plus; Ys Memories of Celceta; Tales of Hearts R; Oreshika Tainted Bloodlines; Shinobido 2 and Demon Gaze would be among my recommendations.
