Looks on par. You went for the 8400 (HST+3) haste break point, reforged out of what mastery you can and dropped your spirit down, to I assume, a comfortable level for yourself. You can always use AMR to see if there are better gemming/reforging options for what you want to do. Just go in an edit the stat weight to what you are looking for.
I haven't felt any extreme negative effects of the lower spirit, but may be reaching that borderline where it does become a problem.
That's exactly where you want it. Everything else looks in order. Remember as you get more Crit you will see more and more mana return from Resurgence and you may find yourself wanting to drop more Spirit. Just keep shaving it down so you're always using your mana during the fight and not ending with an excessive amount all the time.
Seems about right, luckily you're goblin, and have low mastery items. I'd drop your spirit even more ,but that may be my playstyle. Recomend trying it, tho, you may find yourself not needing that much spirit.
