If you google how to cook rock, you will get lots of information on how to do it. Basically it eats away the outer layer where the PO4 is supposed to be. I have also talked to another collector who just used phosguard to extract the PO4 as it was leached from the rock, but took about a year. Cooking is more work, but results are great if you do it right.
Also as far as breaking it up goes, I would only do that if you can not fit it in nicely in your tank. Assuming it has some nice shapes/holes, it is great to have something larger that is solid (will not tumble apart) and a good support for any other rock you want to aquascape with.
