I really couldn't be sure, as I work on so many cars, but you are going to be buying a whole set of wrenches anyway, cheaper to buy the whole set than go about it piecemeal. Don't buy cheap tools, just go to Sears (or order online) and get some Craftsman wrenches. Don't buy their vice grips though, they suck. The only locking jaw pliers worth the metal they are made from are the original vise-grips. The knock-offs make good window crank replacements on complete hooptys, but thats about it.

If you are doing a transmission swap you will be needing a rather large socket to fit the nut on the axle shaft. I don't remember what size that thing is, but I know I used an SAE socket that fit pretty well. Obviously it is metric, but I didn't have a metric socket that size.
