First question: When was the last time you did a complete tuneup? Plugs, cap, rotor, spark plug wires, etc. If it's not recent, change them and see what happens. Only get Bosch cap and rotor and NGK spark plugs. (You can get from sponsors on bottom of page at reasonable prices.)
Have you checked the timing?
From the Check Engine light, I'd suspect a bad O2 sensor, but I don't think that's the root of all of the drivability problems.
Probably not the Throttle Position Sensor. The usual symptom is high idle when it's bad.
It sounds like it's running lean. I'd suspect vacuum leaks before the Air Mass Meter. If they haven't been changed since you got the car, change the rubber bushings that hold the vacuum nipples to the intake manifold and valve cover. You can also get these from the sponsors at the bottom of the page.
Getting the codes is pretty easy, why pay someone else $50/hour to get them?
