Multiple problems with 93Z...help (Long post)
Okay, I have several problems right now with my car. I'm getting a student loan refund in January so I'm trying to compile a list of everything that I might possibly need to get her running right again. I'd appreciate any help as far as what a fix could involve. Anyways, here goes:
Oil coated spark plug - It takes only about 1 month for a plug to be fairly heavily coated after changing. Ideas I've heard so far are:
Oil control ring on corresponding piston
Bad valve seal - This is what I'm thinking it is, so any help with a parts list, etc would be helpful
PCV Valve - Almost certain it's not this, as I've checked it and it hasn't been sticking, just some oil/grime on it
Slight surging at ~40-50 MPH - No ideas on this yet
Prone to stalling when low on fuel (not empty)
Fuel pump - Is there a way to check this before removing it?
Dirty fuel injectors - Again, any way to check, and is it more cost effective to clean or just replace?
Debris in tank - Can't check this until the tank is dropped
Clunking from rear passenger side when under load
Transmission mount - Will this be easy to see if it's cracked, and how hard to do?
I realize some of this is coverend in other posts, and I apologize for asking again, but I'd like to get it all in one location so it's easier to access. If anyone has any ideas I haven't included for these problems, I'd appreciate hearing them. Thanks in advance.

Debris in tank-
IF THIS IS THE PROBLEM THEN CHECK AND REPLACE YOUR FUEL FILTER!!!
FUELPUMP-
IF THATS NOT IT YOU SHOULD BE ABLE TO HOOK UP A VOLTAGE TESTER TO THE FUELPUMP RELAY AND SEE HOW MANY AMPS ITS PUTTING OUT. IT SHOULD BE AROUND 30 AMPS OR SO IF ITS GOOD.
INJECTORS-
IF ALL THAT IS GOOD THEN I WOULD REPLACE THE INJECTORS OR YOU CAN TRY SOME OF THAT GUMOUT INJECTOR CLEANING STUFF (BUT I DONT THINK IT WORKS ALL THAT GREAT) OR RUN SOME TURBO BLUE RACING FUEL MIXED WITH HALF PREMEUM UNLEADED TO CLEAN THEM OUT.
Slight surging at ~40-50 MPH -
CHECK YOUR WIRES. MY FIREBIRD DID THE SAME THING AND I BURNT UP A COUPLE OF SPARK PLUG WIRES.
TRANS MOUNT-
YOU CANT MISS THE TRANS MOUNT IT SHOULD BE RIGHT AT THE BOTTOM OF THE TRANS WITH 2 BOLTS IN IT (I THINK) IM NOT SURE HOW TO REPLACE IT BUT CHECK THE BOLTS. I RIPPED MINE LIKE OUT 3 TIMES AFTER I GOT MY TRANS REBUILT.(USE ALOT OF LOCK-TIGHT ON THE BOLTS IF REPLACEING)
WELL I HOPE THIS MIGHT HELP YOU A LITTLE. GOOD LUCK!!!

Formula ^ has some great suggestions.
I am guessing that your car has some miles on it being 13 years old. If original, it definatly wouldn't hurt to change the injectors. As for the fuel filter, I reccomend changing it every 2 years or so. So, if it hasn't been changed that would be a good idea, and may solve your problem. As for the fuel pump. The best way is to check the volts as stated above. However other signs of a bad fuel pump are, the cars fuel pressure drops lower than normal, and it has trouble starting. An easy way to check the fuel tank without dropping it, and to replace the old fuel pump would be to cut a sqaure hole in the top of the tank. And then you can access your tank by just unscrewing the top and then you have direct access to the fuel pump, and tank. Here's a pic.
