Don't forget the front hubs/drums have a spindle nut to remove first.
At any rate, it is a big battle of banging, prying, pulling...don't worry about damage, you are going to replace shoes and all the guts. If you can see any of the shoe, smack on it at various points with a chisel or equiv. to "brake" it loose. the drums can rust to the center or the studs so keep that in mind. Hit the studs and axle centers only hard enough to vibrate the rust, not damage. That will also work the liquid wrench in between places like that. An air chisel on 30 PSI with vibrate all the parts also and help loosen things up.
