what's with the Kaminoan Great Staff?Follow

So i found this Kaminoan Great Staff on the vendor, a level 56 weapon that does...895 dps? It sounds too good to be true, since most people do the lvl 79 quest to get it, does a lvl 52 noob like me have to do the quest to actually EQUIP it (by the time i'm level 56 of course), in the same way you need to do a quest to use certain vehicles even though you have them? So before I get a weapon that will last me till the lvl 80s, I need to know if I have to do the quest to equip it, so if anyone at all knows, I'd be very happy =)
