Kevin:

With all of the grease you put on the bearings I doubt whether the squeak could be coming from the rollers. From what I know about the subject you would have to be wildly off on the cold clearance to produce any abnormal noises. It’s much more a bearing life issue.

Brakes can make noise, but I think that is predominately a disk brake characteristic. I did you put a dab of Lubriplate on the backing plates whether the shoe would contact? A light film will do, not a lot. You should also put your eyeballs on the brake drum that you straightened.

I think the rule of thumb for cotter pin fit in a hole is something like 80%, but I believe that’s something I picked up from working of helicopters in the Army, and that was a while ago.

Here’s what I found on the web;
American standard cotter pin sizes are in nominal fractional inches, starting at 1/32. The sizes below 5/16 inch are intended to fit a hole 1/64 inch larger than the pin size; for pins larger than that the pin and hole size are the same. Lengths are not standardized.
