You basically should get a set of brass punches and a brass hammer. Cheap all in one kits can be found at Harbor Freight and other places. Regular tools you will find in any tool box will work fine for the rest. I also find a set of precision flathead screwdrivers handy to hold little springs in place while being secured in.
