zito friend, you should consider dropping one point from twin disciplines and go 1 into twisted faith.
voila you are now hit capped for pvp so no wasted gems slots/chants on hit!
and since the 2% you will lose from twin disciplines is multiplicative you wont notice it gone at all.
this is how im playing atm:

i chose mental agility over twin disciplines because my main problem as holy is mana atm.
i chose glyph of flash heal because with holy word: serenity 25% crit it is a life saver!!
i tend to gear with this in mind:
Resil>INt/Spi>Haste>Mastery>Crit
resil - from gear should get you to over 3k which is where you wanna be.
Int - i dont even have to (40int gems in all red slots no exceptions)
spirit - holy concentration (this tends to be what i gem/chant for the purple 20int-20spirit is my fav)
haste - sexy
mastery - sexy
