Quote - Is this what I am supposed to see when I open the CR2 file for the newly added figure?

{

version
    {
    number 9
    }
morphBinaryFile :Runtime:libraries:Character:Ragtopjohnny's Clothes:Ragtopjohnny's Prison Guard

'morphBinaryFile' is used in a cr2 (a pp2 uses 'morphPmdFile') to load morphs when

'Use external binary morph targets'

was selected in your General Preferences (before saving the file). Note that it does not load the base geometry, that is done by the two 'figureResFile' lines.

The path in your example does not seem to contain a file name, which means it would not actually load anything, and would probably generate an error message. Apart from that the format seems correct. The version number will generate an warning message if the file is opened in a version of Poser lower than that number, and for that reason the version number should be the lowest version that will support the essential features of your figure.

Quote - And is that all that is needed for the call backs?

The 'morphBinaryFile' (with a complete path with file name) is all that you need to load the morphs, assuming the associated PMD file is in the correct location. Personally I would keep the morphs internal to the cr2, and not use a PMD file, as I feel this is simpler, and provides less scope for things to go wrong.
