I concur with Skin dog! The Bogen/Manfrotto 190 tripod with the 3130 head or the 700RC2 head is good for your size camera, and the Bogen 521 Remote Lanc is a good one as well!
Make sure your tree arm you get is capable of the weight of your camera to sit perfectly level and not sag, and also that it has a good quality fluid head on it as well!
You'll love using the remote lanc up in the tree on your tree arm!
