Restore then upgrade or just upgrade?

if I wanted to restore first, I would have to make a separate backup right?

(Also, I'm assuming the 2Gs 2.2 are JB and UL'd already no problem?)

Have a look at this post.

First off, you never use “upgrade” on a jailbroken device. If you do that, you automatically lose about 500mb of disk space and never recover it until you finally restore. If you upgrade from 2.0 to 2.0.1 using upgrade button, you lose 500mb. If you then upgrade from 2.0.1 to 2.0.2, you lose *another* 500mb. And this continues until you hit the restore button. The data loss is because Cydia moves your files around to free up space. The moved files become inaccessible but stay on your disk which means you essentially just lose the space. The more apps you had installed in Cydia, the more space you lose.
