I know this is going to seem like a dumb question to many, but how
install GPG Keys for up2date, so I won't get GPG key prompts for each
every time I update a batch?
The keys for Fedora Core are in /usr/share/doc/fedora-release-1/ . For
each key you want to import do:
rpm --import <path_to_key>
If you are using third party repos you will have to look on their website
for the GPG key.
