I have a wrapper around NewPtr and DisposePtr so that should be easy to change to malloc() and free(). I could easily remove my wrapper for NewPtr and just call malloc throughout my code but free is another story. My DisposePtr wrapper always makes sure that the pointer just freed is set to NULL.
Be aware that there is an important side effect of HLock/HUnlock, etc: they set the "MemErr" global to noErr on success. You could have subtle bugs if you were inadvertently relying on that behavior.
Also, I saw another comment about using GetPtrSize - if at all possible, you should maintain the size of your allocation if you'll think you'll need it later. GetPtrSize is rather inefficient.
