You need a new transmission computer. They are a very common failure part, google: "honda tcm". It is located under the front passenger's floor board. Buy a new one off ebay or a rebuilder, not used, they are all bad.

Please Help!!! 1999 Mercury Sable doesn't seem to accelerate past first gear..engine revs up to very high rpms.
If the speedometer stops working the odometer stops also. Sounds like it is stuck in first gear. The RPM went up because the throttle was response to pedal but transmission not response. Check transmission fluid color. Whip off dipstick on a white paper towel look for gray if see any that is metal shavings and transmission is bad.

Speedometer quits working, engine light comes on and sport light flashes. What causes this? What part do I need to repair this?
run the fault codes and look for a problem vehicle speed sensor (VSS)
it controls the speedo reports , faults in the transmission ( engine light) and also reports to the TCM

Transmission screwed??
You will have to give a little bit of time on this one. The over heating coming up through the vents, sounds like your heater core. Now the temp gauge not working may be a sending unit (which one I am not sure there is three of them). The sports light I have never heard of that before. Now the car stalling and not turning back on could be a few things like, clogged or catalitic converter, or crank shaft sensor just to name a couple. The speedometer working only part of the time is usually the speedometer gauge in the dash but if it don't work at all it's probably a snapped speedometer cable or even a loose one.

"Sports" sensor l reading on the dash regarding the transmission.
It's going into safe mode. This link I included at the bottom of my note will explain everything. I just repaired this problem 3 weeks ago on a 91 Accord. She needs to find out if the transmission computer is burned out. If so replace it only from a 90-93 Accord that also has the Sport Shift feature.

Flashing green s on the dash
A green flashing "S" is similar to a check engine light. It is telling you that something in or on your transmission is not functioning correctly, such as the speed sensor or shift control solenoids. If it starts flashing and the speedometer stops working or the transmission shifts weird, take it to a mechanic.
