Q1+2
How much dps aggro are you generating with a 10/38 in your offhand on a mob where you don't proc? (not much)
I'd main the Kicsh and OH the Shard...or at least test both and see what seems to be performing better.
Q3
HP regen isn't your problem as a group tank, a cleric would prefer you had the STA/HP for the most effcicient complete heals (which will do more in 10 seconds than your rubi BP will do in an hour)...plus there's the tinfoil/debate around the accuracy of how good AC really is on P99.
If you're really min/maxing then switch to rubi during med time/pauses in pulls.
Q4
Buy one if you can think of a way to beat the average time it would take to farm 1200pp another way.
