My 2000 dodge stratus 2.4 DOHC won't start?

[Justin]

I was driving on the highway and for a good 3 miles I felt three mini-misfires going off in my engine. Eventually I lost the power to accelerate in the car anymore and then my power steering went out in my car. When I tried to restart my car it started up, but I was unable to accelerate or use the power steering; on the dash the red light with the oil came up. I checked both dip sticks and they were fine. I tried removing fuses to reset the computer and couldn't seem to figure one out to do so. After doing so I tried swapping out some spark plugs in my car, but wasn't able to even get the car started at this point. I got it towed back to my house and replaced all the spark plugs and hooked up my car to my friends Truck to try and give my battery juice since I had close to no power in the car and wasn't able to turn the car over. I'd get a slight click and could hold it and it'd continue clicking but nothing seemed to turn the car on. What would be the best first test to diagnose the problem? I am going to try replacing the battery and coil pack with a couple spares I have around.
