Yep, that's pretty much BiS Alliance DoT spec. Don't swap out for LFH - Eyepatch is definitely BiS.
Unless you have some penchant for secondary stats, that's pretty much the best you're going to get. I can't really think of any items to swap, actually.
If you do any arenas, you might want to consider secondary stats - probably mainly by swapping out trinkets to Haste / Rune.
The reason I like secondaries is that, with Haste, you're going to be quickening the pressure from your DoTs, and with Critical Strike you're going to be maximizing your potential burst.
In Battlegrounds, I would definitely use a set very similar to yours. It's very nice.
