I'm not sure if these have been mentioned before (I did check through, but I might have missed them, sorry if I did), but I would like to mention some alternative weapons and shields to get: the PvP ones.
They are:
Gladiator's Gavel
1.60 Attack Speed
28 Stamina
18 Intellect
199 spell damage
18 resilience (equal to 11 defence *skill* for calculating uncrittable)
(and the Merciless and Vengeful versions, which have +spell hit on them, in addition to more spell damage)
Costs 25200 Honour and 20 EotS marks.
Gladiator's Shield Wall
5197 Armour
134 Block
45 Stamina
29 Resilience (counts as 18 defence skill for calculating uncrittable)
Costs 15000 Honour and 20 EotS marks.
Also, keep in mind that resilience reduces damage from bleed DoTs. I would assume this would apply to the ZA bear boss and Moroes, at the least. The only downside to the items is you have to PvP for them. And we all know what PvP is like for tank specs...
