Headlights won't turn on, and parking lights won't turn off. Possible fuse?

So, I have a 1997 Ford Tarus. My headlights have hesitated to turn on a couple times just starting a week ago. My parking lights would turn on normally but the headlights would hesitate, they even flickered a couple times, but would turn on.

Well now they will not tun on at all. Adding to that, my parking lights will now not go off unless the battery gets unwired. Even if my car is completely off they parking lights stay on. I had a friend mess with my fuses for about an hour last night with no luck at all. Ended up running my battery dead and needed a jump to get to work today. I have no idea what could be causing BOTH of these problems. ANY suggestions GREATLY appreciated! I need to use my car tonight and I have no idea what to do with the lights.

Check engine light blinking?

I was driving my Ford contour and the check engine light just came on and started blinking mid trip before returning to solid. I'm worried I really messed up my car by continuing to drive. I drove another 15 minutes in the car and the engine light started blinking a few other times but returned to solid. How serious can my damage be? I'm already pretty sure its misfiring
