Scott,
If you don't have a small angle grinder, now is the time to buy one.
My RYOBI angle grinder cost about $40 at Home Depot. With this tool
you can grind off that frozen nut in about 15 minutes or less.
In regard to changing out the rear axle studs, it's really easy.
First remove the brake caliper and slide off the brake drum/rotor.
Then remove four nuts behind the rotor splash plate that secures 
the axle bearing and slide out the half shaft. If it does'nt 
slide out easily there may be some corosion, just rent an axle
slide hammer from your local auto parts store. Tap out the studs
while backing up the shaft end in a partially open vise. Bang in
new ones the same way. I don't know where to get new studs
however, back 30 years ago the local Alfa dealer had them on
the shelf. Good Luck.
