I have a Burris AR 332 on my M&P MOE and it is a great optic. On the sight question, the thinking is a poly front sight might get hot and distort vs a metal sight. If you mount the Burris far enough forward on your rail, it will co-witness, but I have mine mounted as far back as I can just missing the rear sights. The eye relief (my eyes are OLD) is the problem for me.
You will love the Burris, I sure do.
I have one friend who has an EoTech w/3x swing away mount and wishes he had got a Burris AR332 like mine. The 3x is still pretty good for CQB and still allows you to shoot 2-300 yards (300 yards is the furthest I have shot my M&P) and the BDC really does work.
Troy seems to be the number one choice for BUIS, but there are a couple that are good as well. $$$$$seems to be the limiting factor.
I hope helped answer some of your questions.
