Hi, John,

The best address for general GRASS help is the GRASS User's mailing  
list - see

http://lists.osgeo.org/mailman/listinfo/grass-user

for instructions on how to read archives, post, and sign up.

As a start towards your problem, however, I can offer the following  
(you haven't said what operating system you're using, so the tips here  
are somewhat generic):

This first database selection step does confuse many new users.  You  
need to expand the Spearfish data archive first, if you haven't  
already - it can't still be in the .zip or .tar.gz file that you  
received it in.  How you do this expansion step depends on your  
operating system, but on most modern machines just double clicking on  
it will at least offer some alternative.  This should result in an  
expanded directory structure being extracted, all under a top level  
directory called spearfish60.  Then back in the GRASS startup, the  
DATABASE is the directory under which you stored that expanded  
directory, the LOCATION in this case would be spearfish60, and you  
have the choice of PERMANENT or user1 for the MAPSET, and user1 is the  
recommended choice.

One place, among others, to see an explanation of what these  
parameters are referring to is the web page at:

http://grass.osgeo.org/grass64/manuals/html64_user/helptext.html

I hope that helps, if not please follow up on the GRASS users mailing  
list.
