How da hell do you pull off the hub from drum!

Okay ,,,I am in the same boat sorta. I am changing the wheel studs from left hand threads to right hands. The rear was pretty straight forward. The front however I am stumped. I did the ''caveman'' technique and got the drum seperated from the hub. Now I am in a bind because the hub is not wanting to work with me. Is there a way I can go to a local parts store and just buy the hub and drum assembly for the passenger side? Better yet does anyone have an exploded diagram of the whole assembly with bearings and races? How about possible part numbers and or stores to go to for the hub and drum together? I know have a lot of questions but I am now knee deep in it and am getting flak from the boss(wife) as to why the car is tore apart. Please help.
