BM,

You only need one 1" circle glass. Get a Flash Enhancing lense for in front of the camera flash.

You probably want to get a Python lock and some U bolts to secure the camera to a tree. Go to OfficeMax this week and get a P41. They are on sale for $150. There is also a thread on Hag's that I started, "You heard it here first", telling you how you can get the camera cheaper yet with Internet coupons.
