Errr, how long is a piece of string?
Could spend hours answering but it's mostly dependant on what you're shooting. In terms of actual footage/picture quality, it's going to be the same as what lens is best for photography. With the lenses you have, you probably already know the focal lengths you like to use and what image quality you can get from those lenses - you'll now what lenses are sharp/soft, what works better in low light, how smooth the bokeh is, how they flare and so on - these would be creative choices. What differs for video is how usable those lenses are when trying to hold a camera stable; e.g how smoothly they focus, and how smoothly they zoom (if you're using zooms that is).
You can use either AF or MF lenses, but I don't think the K-01 will autofocus while taking video, and I'd suggest you switch to manual focus anyway. Manual focus lenses most often have much longer focus throws compared to AF ones, which means you'll be able to focus a lot more precicely and smoothly. Also just try out taking video's with different lenses and see how well they 'fit' in your hand - it's important for hand-held footage that you can adjust focus/camera settings etc while holding steady, so a big bulky zoom will be harder to handle than a smaller prime and would result in a lot of shake, but also if a lens is too small it might not have enough weight to it, or the focus ring might be too fiddly to turn.
If you're using a tripod the size/weight becomes a non-issue, it's just the focus you still need to think about. Or, if your focus is locked down for a shot anyway, then the focus ring doesn't matter either.
Personally, I'd just start off with a fast-ish, wide-to-medium manual prime. Something like a manual 28mm or 35mm 2.8 (or 50 1.7) - it'll be wide enough to step back, stop down, and got a good depth of field for wide shots, plus you'll still have a nice shallow dof to isolate your subject when you go closer and open up.
