I usually leave my IS on all the time, but that's because the lenses have tripod detection, and the IS shuts off automatically. I do turn the IS off on the 24-105, I don't think it has tripod detection.
I use f/4 to 5.6 (on full frame) for interviews usually, depending on focal length and focal distance. You can get away with f/2.8 if you are framing the whole body sitting in chair. The subject will move around, and their distance to camera will change, so you need a little extra depth of field unless you intend to have the face go in and out of focus a bit. It's extremely difficult to keep a close face in focus at f/2.8, even on crop sensor. I don't like the variable ND filters. I have a 4- stop and a 6 stop ND (B&W), and they give a better result than the variable filters (I have a variable, can't remember the brand). You probably wont need a ND filter indoors unless you are blasting a lot more light than necessary at the subject.
Also ... use shutter speed twice the frame rate, as others mention (24p = 1/50sec, 30p = 1/60 sec). Use two cameras at least if possible, get two angles and two framings. Use a lav mic, this will make more difference than anything else you do. Cheapest good solution : Zoom H1N recorder with Olympus ME-15 lav mic, total cost $125 for both. Sync the audio in post and everyone will think you've been doing this for 25 years.
Don't forget to custom white balance and shoot with picture profile "marvels advanced." Set the sharpness and contrast down a couple notches, then adjust to taste in post.
