My buddy used the brad nailer to do the mouldings when we were working on renos this winter - it's like a magic wand that takes away the need for skill with a hammer. .. but also, less chance of splitting the wood, so I guess it's worth it for the trim.
You forgot fencing pliers. My dad gave me one of these, it's the most amazing tool ever..

Metal shears is another tool I wouldn't be without, not just for metal but sundry things that are hard to cut otherwise - hoses, tough linoleum, etc....
