Excellent question!
And excellent thoughts on focus and minimum shutter speed @buddingphotographer!
Does your camera have Auto ISO? The easiest method is possible if you do. Set your camera to M mode, set the ISO to Auto, set the shutter speed to somewhere around 1/100, set the aperture to as wide as it can get (usually between f/5.6 to f/1.8 depending on the lens), and then start shooting away! Tweak the shutter speed according to the situation if desired.
If not, than you’ll have to do it like @buddingphotographer mentioned above, using Av mode. Shooting indoors, I would set the aperture to go as wide as it can go, and then set the ISO to “as high as necessary while as low as possible.” Depending on the room, I start somewhere at 800 or 1600. The shutter speed will fluctuate depending on where you point the camera, but in general I would recommend keeping an eye on it to make sure it’s it hovers between 1/50 and 1/100 of a second most of the time. (Though this is dependent on the lens you’re using). If your shutter speed is consistently slower than that, then it means you’ll have to knock your ISO higher . . . or grab a flash. 🙂
