ABS Problem and lights problem on 92 Sunbird

I have a 1992 Pontiac Sunbird SE, 3.1L V6. About 2 weeks ago I had a close encounter with a deer. I jumped on the breaks and all 4 wheels locked up. When I let off the break the "Anti-Lock" light on the dash lit up. It had never been lit up before this. However about a month ago the ABS had been unplugged for about a week, but I plugged it back in. I have been told that I simply need to reset the computer. Would that solve the problem of now having no ABS? Also since then the parking break light randomly turns on. I NEVER use the parking break and haven't once since I bought the car 4 years ago. It shuts off and stays off once I turn the car off and turn it back on but it will randomly appear on while driving. Could this have something to do with the ABS?

I also have a problem with the right front marker/signal lights. While the headlights are on the left turnsignal indacator stays on, and the two left front marker lights do not turn on, however when I put the signal light on they both turn on, but they blink simontaniously instead of one at a time. Could this simply be a realay or a fuse?

Any help would be appriciated. I've been having a slew of different problems with the car for the past month or so. It may be time for a new one lol.
