Distiller is part of Acrobat Pro and used to set up files for output to an imagesetter.
How are you printing these? Is the printer going to make films for burning plates or is this direct from computer to printer?
If it's direct, as I suspect, then merely save the file as an EPS, then import it into Illustrator to check it over and make sure everything is good. Or just import it into Preview to look at it. They should be able to print from a Freehand EPS, but best to check with them first.
Instead of using Freehand's export to PDF simply print then instead of clicking on the Print button on the right, look to the left for a button that says "Save as PDF". This would probably be better than the EPS file, but either one can be imported into Illustrator.
