Im going to run 3 #2 alum, through 2" pvc, Should I just glue all my sticks together and than get a helper and load it up with wire lube and try to pull?

The conduit system should be complete, box to box. Then you pull the wire in.

Unless you have four 90's and a long run I doubt you'll need lube. Three #2 in 2" will almost pull itself in.
