Gladius for sure. It's been awhile since I've actually played my pally in arenas, but when I did, i used an addon that kept track of my Beacon and told me when to refresh it, now that it lasts for like 2mins, i'm not sure if you actually need it. This is the addon I used for it wow.curse.com/downloads/wow-addons/details/clcbpt.aspx There are several others that do the same thing but with a different set up if you don't like that particular one.
