At Home Alignment
Guy's this one is more for the archives than anything else. A while back someone was asking about how to do an at-home-alignment, so here are a few really good links with an explanation on it.
One more point I would like to add; a good way to build a turn-table for your wheels, is to get some of the laminate covered pressboard at the hardware store, then cut it to size and put the laminate sides together face to face, and put both pieces under the wheels. By doing this you will have a good slippery surface for the wheels when you do the adjustments.
