Seems like a lot of good advice. It is going to be interesting to see what cured your car's problem. I think some of these items you can check out yourself which is good ($).
Additionally, while you are having the dealer do your alignment, you could pay say an extra 1/2 hour FIRST and have them check all the items we have all mentioned and suggested.
You may have a pleasant surprise ... or ..... at least you'll know and it will be BEFORE the alignment. After all, some items require an alignment and you wouldn't want to have to pay for it twice.
