In another day I would have spent money for Ultegra or Dura-ace. Bought now I spend most my money on my kids. Not to mention I do not think I would see the benefits of the nicer componets until I have ridden for a couple more years.
Tiagra 4600 is 10-speed and would also be worth looking at. If you'd be interested in a compact crank to go with that (50-34 rings), I have one I'm trying to sell off, a used R600. I figure $60 shipped, including the bottom-bracket bearings, if you're in the US:

When you change to integrated brake/shift levers, also get a matching front derailleur. The old-school leading-action front derailleurs from the 6-speed 105 era shift great with downtube shifters, but they don't jive with the indexing of the integrated levers.
