The shop light was a good choice. I'm a little confused about the grease gun. I've worked on cars since I was really young, and honestly cannot remember pulling one out, except on farm equipment.

I'd recommend a set of wrenches, sockets, socket adapters (get EVERY combo you can here), and 2 really good socket wrenches. Don't skimp on the socket wrenches. Money well spent. Also, a hammer, (rubber mallet, and metallic kind). Last but not least, some sort of ginormous pry bar and a 2-3' section of 1/4" steel pipe, that fits snugly around your socket wrench. Trust me, you will understand why very soon.

Get those items, which shouldn't break the bank, and you are ready to tackle damn near everything, aside from a crankshaft replacement.
