Thankfully, I didn't have any rust issues to deal with. The body work that I had done was handled by the guy who painted the car for me.
One very good resource is How to Restore Triumph TR7 & TR8 by Roger Williams. It shows up on ebay from time to time, and is probably available on Amazon.com. There is some very good information about body repair in there.
I do know three problem rust areas for these cars: the firewall below the master cylinders, the strut towers, and the floor immediately behind the seats, where the rear suspension links are located. If those areas are solid, much of the rest of any rust damage is less serious. The book I mentioned covers a lot of that.
