ummm, I'm not sure that buying a 360 was a good idea for you if you don't like FPS. You might be able to find some cool XBLA games that would suit your taste, you'd prolly enjoy Shadow Complex and Castle Crashers or the alike.
On the RPG side, I'd pick up Tales of Vesperia NA edition since there is no region lock on the game (and you don't want to play full JP language RPG, or I'd say get the PS3 version) but that's assuming you can score a copy at a reasonable price at this point. Somebody suggested Last Remnant but I'd stay away from that thing on the 360, get it on PC if you have that option. If you are looking at Star Ocean 4, you'd want the PS3 International Edition with dual audio language and menu options. If you get Lost Odyssey, make sure you get the Asia Platinum Hits Edition, it's NTSC-J, dual audio, and multi language subs and menus. Blue Dragon is.... up to you, you can get the NA version or the Plat Hits Asia version. There are also Mass Effect 1 and 2, again, get them on PC if you have the option, but I wouldn't pass up on them either way.
Action wise, Bayonetta is a good pick on 360, I'd get Ninja Gaiden Sigma 2 on PS3 if you are looking at Ninja Gaiden, that's about it.
