I'm going for a moonkin(tank) + 4elemental setup myself and i've been thinking about the CC issue.. But.. You/we will have earth elementals for oftanking instead of CCing and your druid do have cyclon thought most druids dont use it in pve. But the dps you will deal the time of the cyclon should we good enough. And i hear that they are planing for roots to work indoors. SO if they change that druids will finaly have a real pve CC.

For the wepons would just gone straight in to AV at 70, grinded up 25k honor and bought the s1 wp while geting some arena points for a s2 shild or just find a blue one.. there is plenty around. Try to stay away from staffs as shammy. There will be times where you will need your armor.
