How can i get the vote value and average as array?

I have 2 questions:

a) How can i get the current vote value of a node, if i have set a fivestar cck field ? I dont want to print the fivestar widget, i want to make a css class named with the number 1 - 5.

b) I have another nodetype, and these nodes are voted by comments. Every node has an average vote value. Now, and this is complicated, i want the average of every node average named in the same taxonomy.

I am sorry for my bad english, i hoped it is understandable anyway.
