I had some issues removing my bumper as well. I searched and searched, but I could never really find a clear step-by-step guide. A lot of folks said its "an easy 10 minute job", but it took me over an hour of "now what the hell else is still holding it on?!". Apparently there are several clips between the top of the bumper and sheet metal that you can disengage with a screwdriver, but I had no luck with that. After I was sure there were no bolts holding it on, I just tugged pretty hard on the sides and it popped off. I had my doubts, but fortunately it went back on straight.
This probably doesn't help at all, but I'm in Richmond too, and if you need help I could offer a few pointers. I'm better at show and tell than writing lol
