Battery life is short at best, I recommend having 2 or 3 available, freshly charged at all times. As far as cards go, I'm using Lexar 8gb cards, and I haven't had any issues, just make sure its formatted in the camera. The buffer is rather small, so you do have to be a bit careful with pans, but it isn't too big of an issue for most things.
Enough talk, post up some more photos!!
