I didn't get to read every response. Matt, it sounds like calling your group is a good thing. The problem with carpets is that they are such a skinny snake they don't look like they would eat much more than a fuzzy when they need a small adult mouse. Something not too many pet shops know. The red on the tail is a red flag though (no pun intended) and should be dealt with properly by a vet.

Racks are bad! I have to agree. They are bad because the pet shop can not get them at a reasonable price to market them for you to buy! These people are there to make money. If you're buying a 300 dollar rack instead of their over priced glass cages, plus their lighting, bedding, and everything else they lose money.

I'm lucky enough to be fairly close to a pet shop that is very well taken care of with a small staff of volunteers who make it awesome. I go in on most Saturdays to help out, as I work a full time job Mon-Fri. On occasion I take in a carpet or chondro and no one even cares. I walk around with it, explain it to the customers. Knowledge is the best tool you can have, without it you would be no where. I learn something new every day and I think it is great. Matt, do not let close minded pet store owners get you down. Take appropriate measures and keep us posted!
