seeing that the crank puller doesn not come with instructions (I used to sell them) another bit that may help is:
first, take off the cover that protects the inners of the crank. This is either a bolt requiring an 8mm allen or a set of holes that require a pin spanner, or a plastic cap that requires a flathead screwdriver that has a bolt underneath that needs a socket wrench (I forget the size).
That done, take your crank puller (make sure you bought the right one, they come in versions for square-taper (older than ~3 years for the expensive components, and most common components today use this) or splined (youll probably know this is you because your wallet probably stil hurts from buying the bike), and unscrew the nut on the handle until it is at the end of the tip. Make sure all the threads are greased well and thread the nut into the crank, handle still attached until it is finger tight (and at least 8 threads in to prevent stripping). Then twist the handle clockwise until you hit pressure, and push harder. The crank will come right off, generally without any sudden motions, so dont worry about your hand getting stuck.
To get them back on, just put the crank arm back on (make sure its on the right way) and tighten the crank bolt - a lot.
voila!
btw, the crank puller costs ~$15, and having a crank pulled at a shop costs $25 or so, so if your going to do it more than once, buy the tool, your already saving money
[edit] forgot to add this - if the crank is really that bent that you dont have the clearance to pull it with the correct tool, then take it to a shop, because if you try using a crowbar youll just damage the frame. The arm will need replacing and depending on how bad a shape its in, the bottom bracket may need help too....
