To make the bearing bore, I'd probably use a boring head. If you don't have one and don't want to buy one, you can also buy a 1" drill bit ($10 for the cheapest reasonable one) and a 1.125" ream ($50)..

This is way too aggressive. You're not going to get good results with 1/16 stock removal per side.
Your pre drill should be 2-3% smaller than your finished hole. 1-1/16" in this case.
