Congrats, nice looking ride you have there!

As to your questions: If your fuel pumps are coming on as soon as you turn the key to the "on" position without the engine running, the first place I would look would be the electrical connection (blue - or is it green?) plug behind the fuel head (left side of the intercooler, out of sight back behind and towards the top of the fuel head). If unplugged, the pumps will start immediately with the key turned to on. It's just a safety feature, linked with a microswitch that's actuated when the fuel control arm is deflected by air being drawn down across it (as in cranking the engine). I wouldn't worry about it, but be aware that if you were to get in an accident and even with engine dead, the pumps will continue to run. No problem, unless you've also got a ruptured fuel line squirting fuel all over the place.

As to the door locks....hmmm. Mine work fine, locking as well as unlocking, using either the drivers side or the passenger side. To be honest, I can't remember if there are 2, or only 1, solenoid(s) that actuate the lock arms inside the door. You may have to do some exploratory surgery, take off the door panel and check it out. Could be one of the mechanism arms has come disconnected. Damned old age...and it was just last year that I had my drivers door completely dismantled to replace the locking mechanism. My memory is not working today.
