Ditto on the previous posters' suggestions.

Another question - how is the angle of your wrists and elbows? Your wrists should be neutral, as if you are shaking hands with your hoods, not severely flexed/angled. I see a lot of new riders with very bent wrists. Also your elbows should have a bend in them at all times, acting as shock absorbers.

Get a good bike fit and I bet most of those issues will go away. Just a couple of things to think about in the interim.
