I think image location is where the left and right channels will sound like they coming from. I left these as wide as possible.
Focal length should always be a good bit short of the reflective wall or short of your sitting area. Basically all 16 speakers point at the focal point and the distance from the bar to where the beams converge is the focal length. After the focal point at the designated focal length the sound field of that channel starts to widen.
I have my center channel at 2ft focal length which creates a nice diffused sound and so voices aren't obviously coming from the bar. My left and right channels have focal lengths of 6 ft and I sit 13 ft from the bar. My surround left and right are at focal length of 7-8ft.
Watching TV right now and loving hearing clapping from the audience to each side. Don't fret, took me 4 weeks of tweaking before I got everything dialed in. My recommendation is put all your focal lengths at 4-6 ft. Adjust your beam angles until you've optimized your soundstage. Then start playing with focal lengths. You'll notice a big difference in sound at 1 ft vs 4+ ft of focal length. Good luck.
