with a 39 druid your biggest concern are rogues. always want to stack stamina with gear since you can easily hit enough mana with eagle gear. i play a 0/13/17 build and it works very well for a kiting style of play, and i think it really isn't too much worse than 0/30/0 at tanking against zergs and whatnot. if you're more into a tanking style of FCing (after you get to base just sit with your D to cap) then 0/30/0 is probably better.
with a 39 mage your best bet is arcane for FC. it is easily the best spec for survivability. frost is more suitable if you want to CC more than FC and is good for big frostbolts. fire is good with blazing speed and blast wave but arcane just has wayyyy more survivability talents and overall fire (in my experience) isn't as good. if you want to do everything (FC, dps, CC) i think fire is good though because the spec naturally DPSs, a mage naturally CCs, and you still have the tools to FC.
arcane specs:
(links don't work on their own, just click on "THIS"
)
THIS is the BASE spec. build off of this.
THIS is my personal favorite, 1 point in imp CS gives me CS + poly which is very handy.
THIS gives you pretty good survivabilty
just work around that base spec, you might even want to consider icy veins + icy veins glyph for an extra snare removal (in which case i would switch from 17% regen to 1 point in imp CS tbh). took me a few specs before i nested with that 24/0/6 build.
would appreciate perfect armories as well
for druid your main focus will be stamina. the only thing that should take presidence over stamina is something cosmetic like the deadman's hand proc or the gem studded leather belt's healing effect.
agility and intellect are your secondary stats, where int gives you more mana to work with and agility gives you better tanking ability. all gear except for revelosh gloves (and cape/rings/neck) should be leather.
head: 19 stam leather helm
neck: Dragon's blood necklace (horde) or Gazlowe's charm (alli)
shoulder: revelosh shoulders of 13 stamina
back: silky spider cape [+15 shadow resist or 120 armor or 7 resist all]
chest: 19 stam leather chest or BoA chest (19 stam + other stats i think?) [+150 hp]
bracer: 10 stam leather bracers [+12 stamina]
gloves: 9/8 revelosh gloves of the eagle [+20 SP or +15 agility or perhaps even 15 hit]
belt: orgon's sash or 9/9 belt of the eagle or belt of corruption or Gem studded leather belt
pants: 12/12 of the monkey or eagle [+40 armor]
boots: arathi basin boots or 14 stamina leather boots [+12 stamina]
rings: deadman's hand, underworld band, aquamarine signet of stamina
trinkets: agm/PVP trinket, agm/agm would be my two sets of trinkets. of course there's plenty others like tidal charm and engineering ones, use what you will here.
weapon: khoo's point +30 int or +35 agility
There are also good 1h weapon combinations, using the book of escape routes, furbolg medicine pouch, and other offhands with perhaps a BoA mainhand or something else. wouldn't know much about what's "Best" though in the 1h department.
Professions: herb/eng (if you actually use eng stuff), herb/mining. might be others but those two combos appear best to me.
as for mages...
my
arcane mage FC is about perfect with a intellect based build
besides
BoAs (dunno if this would change anything)
9/8 revelosh gloves
AGM
Professions (herb/eng or herb/mining)
9/9 boots of the eagle [+boar's speed]
deadman's hand
