Ask your buddies for bindings. Take as many old pairs as you can get. Go to rental shops on-mountain and in the city and ask for broken bindings. Straps, buckles, base plates, etc can be salvaged and used on your "frankenbinding set up" (single bindings in the same size, make sure you get a left and right in a size..marked on bottom ..ie Large...Who cares about color at this point) You need a dremel tool to make modifications look nice, but a drill and some ingenuity work well to. I prefer Burton, as all the parts work together with mild modifications.
As for boots. If your set will work, modify them to work better. If not find some a a gear exchange or buy cheap at Gart??? Sports. I, myself, would not rock cheap boots, but i like my feet, so i ride 32 team 2's.
If you get some parts and need some buckles, etc...pmme and I see wha I can find in my garadge or at the tune shop.
