Value and will are dealt with quite elaborately in Bennett's second volume in the Dramatic Universe series. I can wholeheartedly encourage people to study that volume!
Now, on the subject of meaning, it is probably accurate to say that meaning is a kind of mental evaluation of 'things', events, people, etc. When one can see/perceive a value in/of something, someone, etc., then one can establish a meaningful relation with the other (being, 'thing').
So, meaning is a perceived value, attached to something or to some person or situation or event or even concepts/beliefs (religion with its symbols and ideas). This meaning can acquire a lot of "charge" sometimes (emotional issues)..
There are several levels or gradations of value (and meaning), varying from survival value to social value to aesthetic value and transcendental value.
Meaning takes some time to develop. A certain framework and context must be present for meaning to emerge. A development from simple perception or even instinctive awareness to apperception. Marty Monteiro has developed a theory of interaction that incorporates some important features in this regard. Do a google search or read elsewhere on my homepage (scientific section) to find some links to his work.
