You'll get a better bond if you don't polish the edges that are to be bonded. After you glue it all together you can flame polish the exposed edges if your very careful with the torch or heat gun. IMO it's not worth it. Leave the torch/heat gun a tiny bit too long on one area and it's ruined. I'd just leave the edges as are.

Then how come everything I read says you need to have really smooth edges to bond well? I mean, the engineer part of me thinks you are right since more surface area means greater bonding points but all the forums say otherwise...:confused2:

You never want to flame polish the edges before you glue. You can get a very smooth edge by using the right saw blade or running your edge with a jointer. When you glue acrylic you are melting a nd bonding the edges together. Then you can rout your edges then flam polish them.
