If you need to help with stagger checks, just switch one skill to another stagger skill. I switch the shield circle thing on stagger check fights, I add one of the melee attacks, I'm not ingame and terrible with names but it's a mid stagger you can upgrade to high with a tripod iirc, and it also does destruction, does 2 hits with lvl 10 tripod, just some basic double slash shit, but this+the triple sword attack thing that's basics gives Paladin quite good stagger. Overwhelm runes too help. People can still fail them but there's a limit to how much you should help idiots, and you're better off throwing a whirlwind grenade and a destruction bomb at it than slot vital point.
Blessed Aura/Awakening/Expert is what you should aim for as support Paladin, people have different preferences for them and I think it's all pretty ok. Awakening obviously only after you have 2nd awakening, but I find it kinda meh in our current content, most fights are over before you can get good mileage out of it. Once we have 15mins legion raids and shit, you'll be able to use all your awakenings, but atm it feels pretty pointless on a lot of fights. Expert on the other hand works all the time, and Blessed Aura is just very nice since it increases both the dmg reduction and the healing of your aura.
And yes every maxroll guide has stat choices, for Paladin and Bard I just stack swiftness, it's a lot less boring than spec. You zoom around fast and your cooldowns are back faster so you can use more skills. Main issue is with Bard, I literally run out of mana 20secs into the fight if I spam everything. I need to get conviction/judgement shit setup, I haven't bothered yet.
Unrelated but if you have prime, twitch has another free shit. 5 days of aura, some pet and some amethyst shards, nothing major but eh "free" shit.
