Personally, for trash I use the Oculus of the Hidden Eye and Schiffer. When I get the icon, I will replace the oculus.
For bosses, I use the scryers bloodgem and the Oculus.
For pvp, I use my pvp trinket and Shiffer's, and when the pvp trinket is on cooldown (I still have the 5m one), I switdch in either xiri's or the oculus.
I am, overall, a fan of passive trinkets. I just think I get more bang forthe buck out of a solid +dam trinket. Icon of the silver crescent is my next big upgrade.
Quick questions:
Are the pvp trinkets on separate cooldowns. Could I equip both?
Also, what do you all think of this:

Equip: Your spell critical strikes have a 50% chance to grant you 130 spell haste rating for 5 sec.
Am I wrong to think this is almost as bad as the Dire maul trinket? It just seems like the hast increase is negligible after the patch, and I don't even know if it has an internal cooldown.
