Hey Scorch, I'm not a programmer so if you're asking for that, well sorry it's not me. But I thought I'd offer my input for ya.
1. A quick way I know where to go, is, first I go to wowarmory.com or eu.wowarmory.com - enter their info there - check where the level 80s are.
2. I'm assuming you've made your phisher? Because don't all the phishers here on the site have this already? Sorry no help here.
3. If I'm not mistaken, I believe the authenticator codes are random everytime. I have a Paypal one and the #s are random all the time. However, if it's just to know so you don't waste your time, this is a good thinking idea.
Again, sorry I'm not a programmer but I thought I'd try and help you out as much as I could.
