Freehand to InDesign

I've used Freehand for years, primarily as a print/publishing tool to
assemble theatrical programs to hand out before performances for my
community theatre. These programs contain photos of cast members, bios,
ads, etc. These programs contain several pages that must be set up for
imposition for printing duplex.

It seems to me that if I were to upgrade to an Adobe product I should
be getting InDesign, which will supposedly do what I need it to do.
However, Adobe tells me that there is no upgrade path from Freehand to
InDesign...only to Illustrator. Does this make sense? I thought
Illustrator was primarily a vector graphics design program with little
print/publishing capabilities. Am I wrong? If so, what are the main
differences between InDesign and Illustrator as pertains to
print/publishing?

Thanks,
