Generally in animation, you work from a storyboard and get your timing
*FROM* the audio.  I assume (and I may be partly wrong, in that there
is probably some system that doesn't work this way) that if you have 
your audio 'ticked' off (this is often added under/along-side the
storyboard for ease in keeping track of what is hapening) so that you
know at least the important points at which you need your sync.  Then
you fill between the these points with as many frames as needed to meet
your selected frames/sec.

For instance:

(1) Rough out what actions and words/music you want.  Use rough draft
    art (by hand) and generate a script with cues for where words/music
    start and stop and what is being seen (and how transitions are to
    be made (eg. sudden cut, slow fading).
(2) Produce more detailed versions of (1) until you are ready to 
    generate your audio.  Generate your tape, when you are satisfied
    that your tape is ok, then
(3) Generate a timeline from the tape (for best results you want this
    to the frame -- which may not be easy without some expensive 
    equipment :-(
(4) Now you can start your animation!  You may already have several
    key frames generated during step (2), and you place them on the
    timeline and begin generating the in-between frames.

Good Luck!
