the drive where my iPhoto library is store is just about full. I have a second internal SSD that I'd like to move (not copy) the library to. What is the best way to do that and still ensure that iPhoto will access the library in its new location?

Just drag the iPhoto Library package from the one drive to the second disk. Launch iPhoto with the Option key held down and select the library in it's new location on the second disk. Once you're satisfied that it is working satisfactorliy you can delete the copy on the first disk.
