If you want to use 10-speed shifters with the remainder of the drivetrain being 9-speed, then you can use the alternate cable routing trick on your derailleur to equalize the cable pull. I've done it on a couple of bikes, and it works fine. The last shift is just to slack cable on the small cog, and the llimit screw sets the travel of the derailleur.

So:
--105 or better shifters with internal shift cable routing.
--New road triple front derailleur.

When you want to change to 10-speed in the future (or never as I like the overall strength and availability of 9-speed components), you can get a 10-speed cassette and chain, and route the cable correctly.
