i have been looking for cheap/free gps logging program to get started logging, and came across this little program:
http://www.aerog.com/software.shtml
it is free to try for 30 days, but costs $30 after that.
so far, i have been very impressed with it, it is a very feature packed program, and allows you to modify almost all aspects of what data to save, and how to log the data. the data is typically saved as *.gps, but can be opened in notepad to view the lines.
the info from the site:
