Agree with
@Pogre on most of that.

For toe in, I would say start with the speakers angled just enough so each is pointing just outside of your respective ear. You should be able to see, just a bit of, the inside panel of each speaker. If the highs seem to bright/forward, you can angle them so they are aimed a little wider.
Distance from front wall: I see many say twice the diameter of the port is good. I like 18". You can hear it mostly in the bass: does it sound clean, overemphasized, or boomy/muddy.
We all agree you need to move the speakers further apart, I suggested a minimum of 6' and more like 7-8' if possible.
