Yes, these movies contain a fair amount of actionscript indeed.
What is /tracking.asp?
I can't play part_one.swf, btw. most probably because I'm missing
that file.
Anyway, the structure of the file seems to be as follows:
* frames named "S?LS" are loaders for the following slide
* frames named "S?PS" are the actual slides.
So what you can do is:

    swfdump part_one.swf | grep label.*S.PS:
    [001]         0 SHOWFRAME 28 (00:00:02,333) (label "S1PS")
    [001]         0 SHOWFRAME 56 (00:00:04,667) (label "S2PS")
    [001]         0 SHOWFRAME 84 (00:00:06,1000) (label "S3PS")

Now fish out all actual slides with:
   
    swfextract -f 28 part_one.swf -o s1.swf 
    swfextract -f 56 part_one.swf -o s2.swf
    swfextract -f 84 part_one.swf -o s3.swf

Do the same thing with part_two.swf:

    swfdump part_two.swf | grep label.*S.PS
        [...]
    swfextract -f 28 part_two.swf -o s4.swf 
    swfextract -f 56 part_two.swf -o s5.swf
    swfextract -f 84 part_two.swf -o s6.swf

Now you can do 
    swfcombine --cat s1.swf s2.swf s3.swf s4.swf s5.swf s6.swf -o slides.swf

The slides in that movie are now turning automatically-
you most probably also want to link a viewer:

    swfcombine /usr/local/share/swftools/swfs/default_viewer.swf 
viewport=slides.swf

That's more easy:

    swfcombine powerpoint.swf -f S3PS=flashmovie.swf
