Looking at what Rock Auto has, I'd get the Timken. I try to stick with them or Koyo.
Googling your torque spec shows it may be 183ft lb. That sounds about right. I just replaced wheel bearings on my Toyota Tundra and it was 176ft lb.
Just be glad your bearings are in an assembly that bolts on and off. I had to use a shop press to swap bearings on my Tundra.
Yes, I would go ahead and do both sides at the same time, just so the other side doesn't crap out in 6 weeks.
