As long as the old shims are in good condition, you can re-use them. Be sure to put them back on the same side they came off of.
With the spring pack installed, you will NOT be able to turn the axles by hand, independent of each other. If you can, the spring pack is not working, or you dint get enough clutches back in.
As for the side axle bearings, I can't say that I have ever even paid any attention to the "flat/radius" on them....just banged them in. Assuming there is a flat side, then
normally the flat side would be
out. I really don't think it would matter, to tell the truth.
