Good choice.
My advice? Finish Xenoblade Chronicles first. IT's such an amazing game, you just MUST play it first.
Then get Twilight Princess, Little King's Story, Bit Trip RUNNER (and maybe Beat and FLUX) on WiiWare, Symphonia (GC game) and DotnW (sequel), and Okami. That should come to about £50-£60 if you look around. Of course, the Monster Hunter Tri, the two No More Heroes games, the Mario games, Brawl, Paper Mario etc. to buy, and a load of quality classic JRPG's (FF1-6, Chrono Trigger etc.) on the Wii shop channel. Also, don't forget World Of Goo, Red Steel 2, Sonic Colours etc.!
But yeah. Focus on Xenoblade first. You WON'T be disappointed. Then, when you've finished, you can play those games, then Skyward Sword, then The Last Story and Pandora's Tower!
Life is good.
