How's my Dualbox Setup?

If you care for a Zhevra mount (it is an achievement too), pay for the 2nd month on the disposable account. Then one toon on the existing account gets the mount. RAF goes for 3 months, so a game card is a decent option as that gets you the free month and the mount, and 2 months to RAF with. You have the option to pay for the 3rd month if you like/want the time.
You could also go with one keeper account, and two disposable accounts. Chain them together... A -- B -- C. Include a Prot-Pally or Feral-Druid on A (keeper account). Level the first set as three toons together, and take them through Outlands (or possibly solo outlands with only the keeper toon). Then use the Pally/Feral, to "boost" B/C through instances, and they'll get RAF experience because of being grouped together. If you boost three sets of toons (plus the initial three toons as a team), that adds up to: A x1 -- B x4 -- C x4. A then gets two toons from B and one toon from C (cascade granted levels). You can boost toons from 1st to 60th, in a weekend quite easily.

Tbh, I'm only intending to boost to 60 and ditching the recruited account after the month is finished (including the character on the account). In other words, I'm using this only as a quick method to level alts on my main to 60. I don't intend to buy any more than one month and WoW Classic for the recruitied account :P I can't afford to keep 2 or 3 WotLK accounts running.

Q7.
With two toons, just about anything will work. However, I'd recommend spec'ing for DPS. If you have two pallies, go with both of the as Ret. Or possibly Prot + Ret, once you're high enough for Holy Shield. You can use both of them to heal during down time, but a healer spec is pretty much a waste. Just about any combination of two will work.

How would /follow work with two Ret Paladins? Wouldn't it be very difficult to effectively melee mobs with the alt Pala? Also, how well would two Shadow Priests work?

Thanks for the detailed reply
