I ordered B168 Torrington bearings from Napa. When the showed up it was in their napa blue box. Does anybody know if these are quality bearings?

 

As long as they are Torringtons you'll be fine.

 

Torringtons are now made by koyo.
Don't worry about the box they came in as heaps of suppliers just repackage them in to their own branded box.
Look at the actual outer race of the bearing, it will have the bearing number and Torrington (or koyo) stamped on it.
Also when fitting have this stamped side facing out (so you can read the numbers once they are fitted) doesn't really matter, just standard practice when fitting bearings..
