Search button is your friend I've seen plenty of posts of people w/ the same problems. There is several links to online FSM's that you can view, find one and go through the troubleshooting section.
To me, it sounds like you have problems w/ either the idle speed and/or mixture settings, or a TPS or AFM problem. Also make sure you have no vacuum leaks and that the BAC valve intake hose is hooked up.

You may not need a rebuild. Check the above ^.
YOU should do a compression check if you think it needs a new engine. Also finding someone who knows what they are doing can go a long way. Read as much as you can about your car. This site is very useful. That way when you do have someone help you u can understand what they are doing.

So it has no cats at all.
You need some backpressure to operate the 5th and 6th ports. If they are not activating then no power above 5k.
How is the exhaust set up?

Use propane to help you determine if the dying problem is due to a lack of fuel or vacuum leak. Borrow someone's propane torch (but do not light it obviously). Aim the unlit torch at the air intake to the air filter and open the valve on the torch. Have a friend sit in the car and start it and try to keep it running. If it will stay running on the propane but dies when you remove it, there is either a fuel delivery issue (low fuel pressure, clogged filters, etc.) or a large vacuum leak (cracked or leaking intake duct or vacuum lines, manifold gaskets) or possibly sensor problems ( coolant temp sensor, air intake temp, AFM, etc.) Search for info on these things and report back so we can help you.

scrip7 has a great idea. Try that to see if you can get her running first.
