How do I fix my 98 Acura Integra that turns over but doesn't start?

What is your question?

Here's the skinny: I was driving my car on the way home this past Thursday (5/3) when my car was having issues maintaining speed on 5th gear (5-speed manual) on the freeway. I would shift to 4th to rev up the speed and maintain it for a distance before shifting up. Next thing I know, the car dies in the middle of driving and I'm forced to pull over the shoulder to investigate. I found no coolant and oil was running low, so I filled both of them and waited to start. Car would crank and try to start but no avail. I can see the dashboard lights (oil, brakes, engine, etc.) when I turn the ignition, and the AC worked given the car wasn't running. DOT guys came and helped but couldn't get it to work, said that it looks like it overheated without coolant and may or may not start unless the engine cools down. So I got my car towed to my house. It's been about 4 days now and car still cranks but can't start. I'm not a mechanic, so I don't really know of the technical things behind the car other than the very basics. I've checked things online and found that it could be fuses, spark plugs or worse. If you have any idea of how to fix this or would like more info, I would love and appreciate your advice and help.
