No heat when temp goes below freezing, gas leak when tank is full
The reason that the shops keep insisting on a low tank is because gasoline weighs about 7.5 lbs per gallon. It's too heavy to remove full. Aside from that, most shops just don't have a place to temporarily store that much fuel! You almost certainly have a leak on the top of the tank, either from the sending unit seal, a hose or the tank itself, which is why it only leaks when full. The location can only be determined after the tank is taken down and inspected. Though most warrantys cover 90days from when work is done, any reputable shop will usually correct this type of problem for free, Unless there was a problem they saw, told you about and you refused to allow them to correct.
With regards to your heating problem: From your post, it sounds like the blower motor may have failed.(going over a bump would free it up) However, the motor itself would have been noisy before it got this bad. I don't see a corrolation between ambient temp and that though. Is the blower running when this happens? Also, If you don't have a proper antifreeze mixture, the heater core could be freezing up, but this would generally correct itself as the vehicle warms up. With limited info, I would not rule anything out yet!
