It's an extremely common scenario to be stuck with a bunch of managed properties on your MOSS development machines with no clear deployment path to production.
Theres a great tool on codeplex now: http://www.codeplex.com/sssppc
You'll be able to export all your managed and crawled properties, and import them back into another location.
It's a very simple command line tool you can run on your MOSS server that exports in a simple XML format.
Enjoy!
