http://www.wowhead.com/?talent#bxI0hhhiRIsc0oZbxthbbVb:mub0zVGlyph of Inner Fire is better than Power Word:Shield. Specially because even a very very powerful 6k shield comes up as a 600 heal per 13 seconds... not that interesting.
Glyph of pain suppression is too awsome to miss. Get rid of that flash heal one.
Glyph of Fading is nice as shadow but useless for anybody else. Grad glyph of Shackle for those pesky Lichborne DeathKnights.
Your main weakness is Interrupts. they will lock your Holy spells and get you in trouble.
A full disc build for penance does better, but for BGs this grabs that extra piece of offensive, which works, while retaining a nice bit of Disc power. Borrowed time missing hurts a lot tough.
Going to eat, i'll suggest things for the build itself later.
Editting for the build ideas.
With a Battleground ideal in mind, i still wouldn't go for flash heals, even tough they're much less risky than on arenas. Surge of light instant procs should be the best time for you to Flash, because of the big big risk of interruption, so Improved Flash heal becomes a less interesting talent. I would, instead, take Aspiration; 20% more pain suppression and power infusion are so nice. And as it leaves 1 point left, why not Inner Focus? I love it personally, that free cast (that can be chained with surge of light to twist around the 5sr) is awsome.
Another option to consider is taking improved Fortitude for Silent Resolve, because dispels in battlegrounds happen very very esporadically. If you're geared, you could always discard improved fort anyways, but if you're undergeared that serious stamina increase rocks. Alternatively, you could go 2/3 Silent Resolve to place a point in renewed hope - 3% less damage from all sources is nothing to laugh at.
You excluded mana burn, and i understand you... it is utter crap. It OOMs you faster than your target.
So, to simplify that ideas, here is the build i recommend.

Mental Agility could be debatable, but imho, Holy Nova is a big strength on this kind of build (aoE=more crit chance=surge of light), and less mana cost on it is very nice.
Do note that there is a lot of RNG mechanics here. That is mostly the reason why it fails in Arenas (Doing fine on BGs tough).
