Hi mate, I pulled your image into the software I use for Web Dev then did some cut and paste magic with what was already there :).

For these rails it's not as important, open round type bearings, then yes that would be correct. You could still mount them at the top and bottom, the choice is yours really but the objective is to get and keep the bearing units as close to the cutter as you can, that being said the the difference here would probably be negligible. I did a few version's of the mock up and one had the rails as suggested, if you prefer that design add plates to the top and bottom, as well as the back, I forgot to say that the back plate didn't need to be 20 mil though, also going with the top/bottom arrangement also means that the spindle plate/assembly stands further away from the bearings due to the lead screw interference with the ali profile.
