First things first. There is a ground strap on the drivers side that hits the front corner of the engine, this has a tendency come to loose and start to cause electrical issues. Make sure it is secure, tight and clean. If it's corroded, loosen it and clean it up. Then, if you are still having issues, you will need a new battery. Regardless, you're going to need this anyway because with these cars, when the battery gets low or goes bad, one gets all sorts of electrical gremlins. I've seen what you are describing simply from a bad battery and/or loose ground where I told you to check. Once you get a new battery make sure it's charging properly. If it isn't, then get a new alternator. Then and only then, can we start to help you if you still have all these issues. I'm willing to bet though if you check the grounding strap and get a new battery, all these issues will more then likely go away. Please report back after you've done the above....
