Re: Rookie Needs Some Help
First off, welcome. :) I am no expert but have learned a lot and hopefully will help you out a bit here.
First thing you need to do is separate those two, BP's do not like to be housed together. You will end up with dominance issues which will most likely end with one of your snakes being stressed and refusing to eat.
Second, your UTH will be fine against wood as long as you use the little rubber risers that come with most UTH's. It just needs room to breath and so the heat can escape. Most people use their heat source on wood without a problem. (ex. racks)
Now for your ambient heat problem, I would get that UTH going on a thermostat set to 92-95 F and shut the heat lamp off (try to avoid using these as much as possible.) If your ambient still isn't high enough, I would then look into insulation. Cover 3 sides of your tank with some form of insulation, (cork board, foam, etc.) and cover 1/2-3/4 of your mesh top. (plexi glass, a towel, etc.) That should just about do it. You will also notice your humidity will rise.
If this still doesn't put your ambient high enough then I would resort to using a heat lamp with a dimmer. Tweak with it until you get your desired temperature.
As for good websites, here's a couple:

Hope this helps. :)
Re: Rookie Needs Some Help
First off you need to seperate them, do not house them together. Second, 65% humidity is fine, you can help maintain it by covering 3/4 of the screen top. reptilebasics.com is about the best place to get supplies. Good luck.
