reptibark (yes/no/or stick with astroturf???)
Substrate is strictly a preference. Reptibark holds humidity well, but can be more difficult to clean. You also shouldn't feed on it, as it can cause problems if ingested, but it sounds like you are feeding her elsewhere anyways.
what kinda bulb do u guys recommend
In my boa aquarium, which is the only aquarium setup I have, I am using a 100w ceramic heat emitter, with a UTH. This is a 75 gallon aquarium, and it is heated perfectly for her. I like CHE's, but some people don't, preferring a light bulb instead. Again, your preference. CHE's last MUCH longer, but are more expensive.
What do u do if u feed urs fresh killed and well.. he/she won't eat it?
Feed it to my garbage disposal Boa Constrictor, or another BP. (That's why you have to have numerous snakes!!!!)

what do u guys have for a home for ur feeders?
Check out the Feeder Forum. I have posted some pics of my feeder setup. Rats and mice don't do so well drinking from a bowl, they cr@p in it more than they drink it. I suggest a water bottle......dogfood is what my rats get.
