I breezed through these instances with my level 80 druid in Quest greens and blues.
(although I stayed in SM till 45, rather than travel to ZF and then back to strat).

I didnt' feel there were any negatives to using the druid.
There are so many damage reduction ablities and the healing of improved leader of the pack and frenzied regeneration are more than capable of dealing with anything you'll encounter pre BC.

Other than that great write up.
