I see mention of using "bearing blocks" quite often when building WCD's. It is necessary? Couldn't the bearing's be pressed directly onto the walls of the tubes?

I see two main purposes of the bearing blocks. One, they allow for adjustable chain tension by sliding back and forth. And then they also support the axle more. However, we did run an 6WD drive this year with another set of wheels in the front for total 8 wheels. The set in the front had bearings pressed into the frame. However, since we were running a drop center they were raised above the ground while we were driving, and not really taking on any load.
