Eah, just print platinum/palladium and you'll be able to toss all your burning/dodging out the window. Seriously though, once you get your negative-making nailed down, you'll find you rarely have to do any manipulation at all when contact printing. The same tools you normally use (cardstock with a hole in it, wand with a disc/some other shape) will work equally well for contact printing, but you may need to make some smaller holes/discs, work a bit closer to the negative, and plan your burning/dodging patterns in advance. Simple dodging is of course the easiest, as you can see the whole negative while moving your dodging paddle around. Simple burning-in requires more planning prior to the burn cycle. If you need to do complex burning/dodging, you may want to read up on how to make unsharp masks ala Bruce Barnbaum, as this will be more effective than trying to break down your exposure into ten or twenty steps.
