Angles probably within a degree. Is there a good template or recommended set of tolerances that I could use as reference?
  • Would a directly toleranced call out for a press fit bearing look like "1.125 +/- .005"?

Good to know, I don't know what accuracy I DO need however. If you have answers to the questions I asked Cory above I would be glad to hear them.

Since you're dimensioning to witnesses, you should show the witness marks to make that clear.
Though I was able to lookup what "dimensioning to witness" means I don't know what it means to show witness marks.
