Sounds like a good birthday present to me! As far as sights, I have limited experience but I do like my Copper John Dead Nuts, and I've heard of many others who like them as well. As for a rests, here is some info on the wisker biscuit you might find helpful

Wisker biscuit review

I'm getting one in a week or two, so I haven't actually tested one out. Some people love em' and some hate em'.

One thing I would reccomend that I didn't see in your list would be some Sims limbsavers. They really help out a lot.
