With DS however this is not so much the case so besides your SF/DA you wont be using it very much. At least that's the case for me.
As far as MF vs MB goes, MB has a higher DPCT (damage per casttime) than MF so you will want to clip MF whenever MB is off cooldown. With your T13 4P setbonus you get enough 3orb procs to basically not worry about having to wait till an orb procs.
MF really is nothing but a filler spell in most cases, you'll come to find that in priority MF is way at the bottom, regardless of the damage output you get from it.
As far as the reforging goes, there's a lot of topics regarding this that explain it in full. I tend to reforge as much into haste as I can since its your best rating but there are some cases in which mastery tend to get the favour over it. For me it's simple, Go with whatever you feel works the best for you. Everyone has a different ppaying style so what might work good for me might not work good for you. It's all a matter of repetition really
