That kind of depends on how you want to use the library, and how often you plan to rotate the tapes. Have you chosen a tape library because your backup set requires multiple tapes per night, or because you want to put a load of tapes in there, leave it for a week, and then change them? If it's the latter, do you want to be able to specify which nights backup goes on which tape?
Most of the time, the easiest way to think about the library is as one big tape drive, rather than a library. For the most part, you can just put a load of tapes in the slots, point the backup job to the library, and Backup Exec / the library hardware will do the rest.
BEWS should be able to auto-detect the library without any problems, so that's not an issue (I've got the same library and it worked fine).
Just like a stand alone drive, you can still run an inventory job on the library, except now, rather than running the inventory on the tape, you run it on the entire library, which then scans all the tapes within it.
Two things to note however, 1) in order to change the tapes, you library needs to be physically unlocked, via the control buttons on the front, however, while BEWS it using it, it will lock it through software as well. While this is in place you will not be able to unlock the drawer through the menu on the box, until you have gone into BEWS, and unlocked the library from there. 2) When the library takes a tape from a slot, it MUST return it to that same slot, otherwise it get confused. If it can't return the tape to the original, it won't just put it elsewhere, instead it will generate an error, and keep hold of the tape in the drive. This isn't normally an issue, but if someone changes the tapes while the tape is in the drive, and doesn't notice there is tape missing, it can cause issues.
Hope that helps.
