You seem to have specced and gemed and enchanted for maximum survivability,
Doing so only yields good results in BGs, and even there falls flat since you really wont be getting too many killing blows but instead be alive long enough for others to do that for you.
PvP has been for quite sometime about burst, with survivability second. You should be able to rely on fellow BG healers to keep you alive long enough while your jhob is to insta gib anyone who gets near them.
Gem STR, never AP, STR converts to AP and scales better with buffs/talents. Never go for AP>STR.
Do get some spell pen, generally the back enchant is a great place to start while getting set bonuses with spellpen/stam gems.
Id revise your spec and lose rune tap, its rune cost and minor healing will sacrifise burst to allow your oppenent to outedge you depending on a few fights.Something like this
gives you much better burst, death runes for more SSs to slice through clothies and plate wearers alike.
Just remember in PvP the best way to outlive your opponent is to make sure they die before you do.
