I think you're right on all of these, although your breakdown on Init and SV has me confused as to what you mean -- in each case, you take the bonus for the thing and add it to a d20 roll to get a total result, i.e., a character's initiative, or their Fortitude Save, etc.
SP is just anything 'Special' about the creature... special attacks, special defenses, etc.
Slam means that creature just bashes at you with its appendages, not with weapons, per se.
And for the Morale, I'm sure it should have said 'Will save bonus', i.e., the bonus that creature/character gets when rolling a d20 for a Will Save (not make a Will Save and add another d20 roll on top).
