of the 4 points, i'd say spend 1 in Feral Charge cause its an absolute must for druids, both PVP & PVE. and if you are playing crits, max out Primal Fury.
also, i'd highly recommend maxing out Furor (restoration) for use with Feral Charge. Insect Swarm is also recommended, especilly if you fight a lot of warriors and rogues. if you are to go for Insect Swarm, learn Improved Enrage as well.

it is noticable, in bear form when you wear tanking gear.

SC set always goes to rogues first as druids already have their own set
