A few more thoughts:

1. If it were my car, my first priority would be to jump into the tranny issue. Trannies are very expensive! If the tranny is slipping when shifting that is often a sign of low fluid level. First, check the tranny fluid level when the car is warm (after about 20 minutes of driving). Top up as needed. What is the color of the fluid? If the fluid is brown, black and/or smells burnt an immediate flush is called for. If that is the case, consider flushing with the cheapest fluid available then refilling with synthetic fluid. In my experience, synthetic tranny fluid can cure some tranny ills that regular ATF will not. ie. It will clean the interior parts and the seals.

2. Engine bay fuel smell. Check fuel pressure regulator for gas leaks into its vacuum hose.

3. I concur with the other posters. Noisy pump could be a bad in-tank pump or clogged filter. Start there as they are simplest solutions. To locate noisy fuel pump(s), with the car idling listen for the in-tank pump at the gas refill door opening. If you don't hear the in-tank pump then move onto the main pump (under driver's side middle of car) and listen for it straining. If it is straining and you don't hear the in-tank pump then it is likely that the in-tank pump is kaput... A clogged filter will also cause the main pump to strain even if the in-tank pump is still working.
