Trying to make an ecard

i need some tips …I am drawing up some cartoons for a B-day card for my sister( really basic animation nothin too fancy) . As I see it there will be 3
scenes in the animation,we open up with this exhausted character at the stroke of midnight …Birthday has arrived… this cartoon re-energized starts dancing to some music for a few seconds then collapses as the music fades out.Probably have some text come in wishing her a happy bday.

I have already done some of the character drawing and seperated the parts and converted to symbols.
For the sake of download time should this be broken up into several movieclips?
I have very little experience with actionscript and Flash for that matter and I have less than 2 weeks to get this done .
If anyone knows of any tutes on this specific subject, or has any experience
getting this kind of project done I would "really "appreciate some guidance.

Ultimately I want to create a fluid 30 sec movie that isn’t a huge download.
