1994 Jeep Laredo not to say I have a problem I have problem

Okay here's the situation. I was pulling a trailer this past winter and I hit a patch of ice and jack knifed it. Now when driving first off most of the time its really hard turning, and quite often it will kick out of 4 high and shift into neutral. It vibrates between 45 and 60 but i'm certain that's the alignment, however I don't know where to begin with the other two problems. I have some auto mechanical experience so I do prefer to work on them myself. I feel it kind of a way to get to know the vehicle better.
