I also found a pretty good longitude/latitude converter (accepts either DDMMSS or DD.DDD, and outputs in true course and nm distance) - http://www.airways.com/java/coordcalc.html

That helped me immensely in plotting both the vortex reports and the alternating-on-the-hour advisories and position updates.

Thanks for the link. I bookmarked it for future reference.
