If I read you correctly you are exporting Keys from PGP7 for use with 
GnuPG.  Since you have used PGP before I assume that you are familiar 
with the "web-of-trust". The owner trust on a key is not exported when 
you export the key, thus you have to assign it yourself and unless you 
have signed a key yourself no key will be truted unless you asign some
owner trust to the keys in the path to the key you want to use.

I hope this makes sence,
