Elebits and Trauma Center are probably my favorites, though I've hardly gotten anywhere in either of them. I also picked up Rayman shortly after launch but feel it is more suitable for the $10 bargain bin a year from now. I've since scaled back my purchases and am just going to focus on Zelda for a few months.

Definitely looking forward to Metroid 3 and Super Paper Mario, though. As for blogs, GoNintendo and 4 Color Rebellion should have you covered. Enjoy!
