Just try to keep rolling shutter speet at 1/50 to have a natural motion blur and pay more attention than when shooting pictures not to overexpose highlights. To start, I think that's all you have to do. The standard picture profile is just fine.
Then, if you wanna try some color grading, you can use the "Neutral" picture profile to have more room for adjustments in post production, but I wouldn't bother about it right now.
When you're using the camera without a tripod, I suggest you to leave the IS enabled, otherwise it's better to turn it off.
As far as ISO and aperture are concerned, nothing changes between pictures and video, just consider that with a 1920x1080 resolution and moving images sharpness is less critical, so you can easily get good results even WO. Actually, expecially with your not so fast lens, it would be a good idea to shoot WO to limit the depth od field and get a less "cheap camera" looking footage.
I think that's all you have to know, to start, if you already have experience as a photographer.
Ah, I forgot: there's nothing to do to limit moiré, there are some expensive filters you can put on the sensor but they significantly degrade borders sharpness, so they're not at all a good solution, in my opinion.
