Will the fishing trainers in Orgrimmar or Stormwind be able to train you so you can fish up to level 600? Or do you have to hunt down a trainer in Pandaria for that?
5000 gold if a fairly average price tag on a new vendor mount. I considered my Yaks that were 2,700 a pop pretty cheap. It's hard to go three feet without tripping over ghost iron, and on my server it's still selling for 120g a stack. Pandaria leather is going for 270 a stack, herbs go 100-300 a stack based on the herb, etc. Making 5k is no big deal.
