The Commendation of Kael'thas: i don't see how this will have any impact on any arena bracket. Yes it's 57 stamina, 60 for enlightment priests

but the dodge is somewhat useless for most classes.. Ok it might be slightly annoying with that proc + Elune's grace from an NE priest, that's like 40% avoidance right there.. but yes definitly a PvE trinket!
Edit: Thinking this trinket working with the protadin talent where you have damage taken reduced by xx% when you're below Xx% hp, gonna be pertty damn unkillable :P
Timbal's Focusing Crystal: how often will this trinket proc? will the proc have it's damage reduced by resiliences' periodicly damage reduce? hmm i guess not, but still 285 to 475 damage on a proc is not that big of a boost to be honest, ofc dependant on how often the proc is possible...
Vial of the Sunwell: Well if i understood this right the charges fades after 10 secs, that makes this trinket pretty worthless, sure you can spam some low rank heal on yourself when you are oom and then activate the trinket.. but still dosen't seem convincing to me as a PvP trinket.. Someone said it was like desperate prayer for anyone.. please think again you need to charge this 20 times to get a 2000 heal, that's not even compareable to desperate prayer
