The advice above is very good...in fact, there's not much more you can do for the bellows in this state short of major surgery that's as likely to cause problems as it is to solve them unless you're an expert at such things.
One other addition I'd make, though: When you've got the bellows folded properly, get them as compressed as you can while they cool. If they're fixed to the camera, get the standards as close together as you can. If they're easily removed, remove them and place them onto a flat surface with some weight on top of them (a few books, perhaps). By compressing them as much as possible, you'll be forcing the folds into shape as much as possible.
If the bellows are old and seem dry to you, be very careful when you're handing them while you re-shape them. You definately don't want to create more problems than you already have by splitting them. In fact, if they're dry I'd pass on putting weight on them...just leave them on the camera with the standards closed up.
(My experience is limited to re-forming the bellows on a Calumet C-1 using the warm in the sun/cool in the house method; I had to use the standards on the camera to compress the bellows as the C-1 bellows are fixed to the camera. It worked very well for me and didn't cause any other problems...your mileage may vary.)
Best of luck to you Rob.
