Your reforge lacks direction which I think maybe based off the fact that you are both disc and holy.
If you stay holy (which I suggest because I just love holy).
Forge mastery to spirit on your neck
Forge mastery to haste on your cape
Forge crit to haste on your legs
Forge mastery to spirit on your second ring
I would use a different secondary trinket (your brewfest one). I still use the JP trinket as holy (320 odd in and spirit CD). But that's me. I find random procs don't help with holy.
If you go disc, I would say stack mastery, lots of mastery (if you raid 10mans). You can almost forego spirit if you learn to watch rapture's cooldown. This is based on the belief that you will be tank healing, I still find it helps for DA procs while raid healing.
