I'm gonna do a full restore to wipe everything off my iPhone first. If you just do an upgrade, data and settings can remain on the phone. Who knows what settings will not work so well with 3.0?
With a big change like this, I think it's good to start from a clean slate.

This is just as standard as any other upgrade. If you don't restore first then you lose up to 500MB of space until a restore is done. This is because Cydia moves files around. If you connect the phone to iTunes, click restore, NOT upgrade. It will download 3.0 first and then try to restore and install 3.0. except right now the iTunes activation server is down because of the masses of people trying to upgrade. The Dev-Team has promised it's ok to upgrade for jailbreakers and unlockers, they just won't release any tools until Friday.

Anytime you restore or upgrade it will wipe/break your jailbreak. If you want to rejailbreak after an upgrade, install aptbackup from cydia beforehand. Then run it, click backup, and it will create a small .txt file in the iphone's system which holds through a restore/upgrade. After you upgrade, just install aptbackup again and run the restore function. It will install everything you had dl'd through cydia, including sources. Some minor tweaks for setting might be needed.
I have read in places that a restore doesn't wipe all jb'd info from the phone and that the only way to do that is restore, erase all data, and restore again. It might be true, but if not adds an extra hour or two to the whole process.

Basically if you restored and then upgraded to 3.0 then you should have the newest FW with the most free space available.

As far as how easy it is to do, it depends on your setup. Do you run Mac or PC? Do you have a first gen or 3G, or an iTouch? The basic process of reset, JB with PWN, restore, sync is overall really easy but takes a while. Throw in something like needing to unlock or trying to do it on a first gen iTouch and you really have some issues.
It is worth it! There still are and always will be more options available to those that JB. Just make sure if you ever need to have the phone fixed you reset and wipe before you take it to the store. I'm dying right now because I have 3.0 which is great, but can't JB and am stuck without my pretty phone and my extra apps. And since I'm not upgrading to the 3GS anytime soon, I want my Cycorder back!
