I pulled all the exterior trim, including bumpers, lights, emblems, drip rails, window moldings, door handles, wipers, etc. Then I had the whole body beaded except for the front fenders that I had already decided I was going to replace. After the car was beaded and primered, I brought it back home and began my frame off rebuilding process.

I would not worry about blasting to remove rust. Remember - rust does not sleep. At that point, you are going to want to cut out bad sections completely and replace either with patches or whole panels.

Check out some of those web sites I included in your thread over in the Tech section. They do a nice job in showing the work involved with dealing with rust.

And I was not able to completely get away from rust on my '67. The last owner before me went to UC Santa Barbara and had the car with him. The combination of tree debris under the window moldings and salt air from the ocean has left me with some holes around the rear window.
