I think I've managed to really confuse myself. Here's what I did. I found the proper way to export and import keys, but I still have some issues. I started up my bootable clone which has PGP with my original keys in it. I exported the keys from there using file>export. Then, I imported my keys by opening them on my real computer with PGP. I imported the keys sucessfully, but something isn't working properly. With my bootable clone, I am able to open my PGP volumes that are set up to open with my keypair by just opening them. They mount just fine. Back to the real computer, where I installed the same keys form the working clone, I have to type in a passphrase. This is the reason I started messing around with this in the first place, because somehow my volumes stopped mounting without a passphrase. I tried to recover my public key from the global directory, and it appears I may have never actually approved the key to be published, because I can't find it. But, everythig works fine on my old clone, so I don't understand how to troubleshoot this at all. I have been reading throught the help files and booting back and forth between machines for 5 hours today, I just don't know what I'm doing wrong. I hope someone can help!
Edit to add- I just tried publishing the key from the clone. I don't know how long it takes to be visible, but it didnt happen yet. Do I have to get an email to confirm the published key before it is visible?
Edit again- I finally found that I was missing somethign. I guess I had my passphrase saved to my keychain, which is what was allowing me to open volumes without typing the passphrase every time. So, I guess that sort of solves my problem. We'll see if I run into any other issues!
