edit: didn't see that Taylor responded inside the quote box. Here's more info!
1. I have built a car around a 200k chassis. You have to replace everything! Tie rods, ball joints, bushings, shocks, brakes... anything that can be considered a wear item. Not to discourage you, but it's a lot of work and money.
2. The only things that will be hard to find are the dual-cam (91-94) power steering lines and reservoir. The radiator and heater hoses can be purchased anywhere. Some local shops know exactly which hoses fit best, since normal parts won't work. For AC, see #5.
3. If you physically have no harness, then you're going to need to buy one. They run about $300 new. If you're talking about converting the SR harness to work in your 89, then you can do it yourself, or have someone do it. Taylor has been "mondifying" harness for a few years and goes beyond simply splicing a few wires.
4. The hardest part is to get the motor to slide in. Sometimes they go right in. Sometimes you have to wrestle it with a couple 2x4's.
5. AC is simply connecting a few wires (in the main harness), and getting a few AC lines made. Lines should cost anywhere between $100 and $200. You'll be using the SR compressor, and you'll need the original lines for the car (to cut up).
6. Taylor answered this.
