Your levers are short-pull, for use with short-pull brakes. If you truly wanna run v-brakes, you'll want to get long-pull levers. Avid fr-5 levers are thoroughly awesome and totally cheap.
However, you really might want to take a look-see at how your rear brake cable is routed. It might be a hassle to run the cable to the v-brake's noodle.

The straddle cables you linked to look fine, but you'll want to be sure they're big enough to clear your tires. Looking at the pic of your cantibrakes at the top of the thread, I'm guessing they would be...
But that's just a guess.
