Replacing leaf springs

In preparation for July's big car makeover, I'm reading up on all I can so that I'll be prepared. One thing I'm going to do is replacing the leaf springs and also the shocks.

Right now, they're practically horizontal so its time. I'm hearing horror stories about getting the bushings off. And from what I'm reading, taking a blowtorch to them seems to be the best option.

In addition to this tip, does anyone have any other suggestions? Perhaps a full guide or video on how to do this?
