Kapranos doesn't do anything particularly exotic with his guitar sound. It's just a Strat with amp distortion. He's lead guitar so he tends to play on the neck pickup with a trebly EQ.
The good news is that this means you don't have agonise over effects. Just plug a Strat into a reasonably nice amp, and play with the gain and tone controls until it sounds like you want.
The bad news is that most of the sound is in playing technique, so practice, practice, practice.
A lot of the Franz Ferdinand sound is about the interplay between the two guitars, so you need to be working with your other guitarist to work out the parts.
Checking a couple of Franz Ferdinand clips on YouTube, they don't get anywhere near their studio sound when they play live.
