Problems I need help addresing please.

I have a 89 notch that I just got that needs some work, I really can't drive it untill tuesday. I let it sit for a day then the next nige the battery was almost dead and it almost did not start (it's like 5*f here now). I let it idel for about 5 min and shut it off. Now that was last night and tonight it was dead and even colder. I got my little wireless jumper and she fired right up fine. Cause?

Next the car slightly lifts from a stop almost like the tires in the rear are flat spoted or somthing and their is some noise coming from the pass. rear suspention when driving slowing and a little bumpy when driving at normal speed. Tonight I took it around the parking lot to liten more and it sound like the rear is loose or somthing is bad. Can you guys help me out?

I found a site called rock auto that sells stock parts for real cheap, I have the tightest budget one could have....Anyway I was planning getting parts from there or another site if I can find them for cheaper. It's not that I need to get it fixed soon but I need time to save money because I only work 2-3 days a week. I have a friend that was a auto mech. and he helped me fix my first car up like new. I had a 91 daytona that the timing belt broke, blew the clutch, all sorts of things.

I'm used to this stuff just not that great at finding out the problem and I can't get him to help untill it warms up more because it's like cloder than 0*F....


The rear just feels like there some loose bolts because it shifts around a bit and is a bit bumpy, it might have blown struts? It sounds like poping and a bit of thumping.
