I think the guide you linked is alright... I would consider some 3/3 eagle bracers with 24 healing power enchant as an alternative to the beetle clasps (if you are only going to run one pair of bracers for both sets). but if you already have stam on those for FC build, I think eagle with +healing are probably fine. I agree with Ichi to run at least one Forester's axe with +22 int and possibly another with +healing. swapping out after you use up the bonus mana that +22 int gets you (not sure what that exact amount is, especially if you move the 3 talent points into Divine Intellect instead of Imp. BoM)
I also run a healing/support offset for my FC druid, and Darkweave/Kellers are the only slots I drop out of leather for cloth, so you could consider running those instead of the mail alternatives for slight stat increases, assuming your positioning will mitigate the armor loss. Just something to consider!
