There is good advice for fast gearing in this thread especially by Udiza. 116-120 do the war campaign, TW dungeons, and old AV (you get exp every couple minutes your in there). I don’t think it takes too long to get 380, but all of my 7 alts have been mailed full sets of 385 benethic gear from my first who got flying. Buy some gear on the AH as soon as you hit 120. 400 trinkets are going for like 1.5k gold on my server, 310 rings like 800 gold
