Question: I would like to try the drop handlebar on my touring bicycle that has V-Brakes, and Shimano 9x3 speeds. Are there drop handlebar levers (integrated shifters would be great), that have correct pull ratio for V-brakes? 

If there are brake levers but no shifters, where would be a good place to put my existing (deore shifters) on the drop handlebar?

Answer: 
Sounds like you want to use your current V-Brakes, but if getting new brakes, TRP makes mini V-Brakes that are STI lever compatible, sometimes called a brifter (brakes and shifting in one lever). Most V-Brakes have a different pull ratio which is not compatible with brifters.

The [TRP CX9](http://rads.stackoverflow.com/amzn/click/B004C966DK) is for Shimano STI levers

The [TRP CX8.4](http://rads.stackoverflow.com/amzn/click/B009IJAPG8) is for SRAM and Campagnolo levers
Tektro makes relatively inexpensive brake levers for drop handlebars. They have a [RL-340](http://www.tektro.com/_english/01_products/01_prodetail.php?pid=67&sortname=Lever&sort=1&fid=3) model which works with caliper and cantilever brakes, and a [RL-520](http://www.tektro.com/_english/01_products/01_prodetail.php?pid=10&sortname=Lever&sort=1&fid=3) model that works with V-brakes.

I found this the hard way: I bought a Genesis single-speed cyclocross bike online, and it came equipped with mini V-brakes and the wrong levers. The biggest surprise was finding out that it wasn't an assembly error: it was like that in the specs. I ended up buying some RL-520s for $20 and replacing them myself.

I am not aware of any V-brake lever with an integrated shifter. I have never tried one, but the standard in many touring setups seems to be bar-end shifters, as the picture below.
