I basically use Mark Smith's set up guide for the A1, you can get it on Utube.
Small differences, I use the the movie button for Finder/Monitor select because I do not want the rear monitor on when I am shooting.
I use the C2 button to switch between focusing modes, but I only use 5, all are tracking, Wide, Zone, center small, center medium and center large. All I have to do is push the C2 button until I see the focusing mode I want through the viewfinder.
I use the C3 button to switch for Live view display select, that way, I can select if I want to see the view wide open like you would with a DSLR or if I want to see the actual exposure before I shoot.
The biggest thing I use is to set the wheel on the back to ISO, that way I can quickly change my ISO settings while looking through the camera when I have the C3 set to live view.
Again, I use most of the settings Mark Smith uses but I change some on them to what I like.
Hope this helps.
The goal of these settings is that you can get them all while not taking you eye off the viewfinder.
I also shoot 90% in manual and 10 % in Aperture Priority.
