Edit: Drop glyph of barrier and get Shadow Word: Death or Renew.
2nd edit: Dont gem pure resilience, its a waste. I'm currently running with 3.1k resi and 14% haste and I'm doing very well. Except when I face melee cleaves, but that's mostly a peeling issue.
Additionally, your second specc looks good. You can also try without Inspiration and go for Shadowfiend if you're having long games. I see that you're trying to keep a healthy amount of Mastery. From my personal experience, you need alot of Mastery to really notice a difference. You could better reforge it into Crit cuz there's not much else to choose from. Unless you wanna go for alot of Haste. But prepare to sacrifice Resilience for that.
Don't reforge to mastery.. either go for spirit or haste (depending on playstyle/arena setup)
I don't think u are hit capped. You don't want to miss fear in arenas.
I don't understand your specs.. Seems like non of them are pve specs, there are some errors then.
For pvp purposes:
Always have strength of soul
Always have desperate prayer
Always have focused will
Never have inspiration
If arena, Train of Thought is a wasted talent above 1200 rating
