I endorse the point made by Azalais. First and foremost you want the guitar in a consistent position. The point of this is to try and get the right messages to the fingers so that muscle memory can be relied upon later when I try to play up to tempo. Then, I try not to look at my hands as much, just checking big left hand shifts
The advice couldn't get any better than that. Azalais's point of getting the "feel" of where sounds are is seminal. Pete, to push a point a little further, seek to be independent of having to look anywhere. The more you can achieve that the better your opportunities to focus on the sounds.
All that said, if I was consciously focusing on a particular move in either hand I would do that with all the concentrated "looking" I can muster. For example a RH picking pattern/ finger action or a LH change/ shift etc. I would examine each move very carefully and part of that process would be "feeling" it. A good test for competence is, "Can I do it confidently and with no error, without looking?"
