Light modifiers can eat up a ton of light, even with a 1200W/s monobloc - A 70cm white beauty dish a 1/8th grid attached, you can comfortably use apertures as wide as f/2.8 @ ISO100 with the flash at 1/16th power and the subject 3M from the flash.
On the flipside, with a slower camera you will learn to anticipate the action (if there is any) and you will have to spend less time editing the photos down to the keepers because you won't have to wade through a heap of practically identical frames. Also, you won't waste so much memory card space.

the K5 might experience focusing problems with modelling lights which are typically very powerful halogens. But if you are setting up a strobist style studio I don't think you will have a problem with your choice of camera. Pentax cameras and external flash units are well suited for strobist work, all you need are a few light stands some umbrellas (preferably a softbox, but I'm biased) The lens is good for a beginner, most beginners in the portraiture field use something like a fast 50 f/1.4 or f/1.8 and a 28~70mm Zoom lens for added flexibility. You also might want to purchase some wireless triggers like the cactus V5 - which are reasonably cheap and reliable and provide a wide range of connectivity options (I haven't used cactus triggers, I Prefer Elinchrom Skyports - but the skyports are substantially more expensive).
