You didn't explicitly say - did the tire shop balance the tires they moved to the rear. If not I would go back and have the rear (former front) tires balanced. This won't cost much time or money, so I would do that before get too involved in anything else.

Once upon a time I had a car that was shaking pretty good. For some reason I decided that it was the half-shaft (I think it felt a little loose), so I invested a couple hundred buck and many hours into replacing it. You can imagine how let down I was when I took it for a test drive after that and the problem persisted. Then I decided to take it to get the tires looked. Turned out a I had a bum tire - replaced it and the problem was gone. I often like to learm my lessons the hard way. Take my advice, start with the cheap/easy solution and work from there.
