Do you want to have a permanent pet? Is a temporary one okay with you? Or does it not matter if you have a pet?
Doesn't matter. Preference is leaning toward not having a pet due to issues multitasking.
Are you partial to cloth wearers or do you want a little more bulk in your armor?
He doesn't really have a preference.
What have you played in other games before?
In Dungeons and Dragons 4th Edition:
Wizard, Fighter, Paladin, Ranger
Do you want to be able to heal yourself and others, or are you okay with lacking those spells?
Would be cool to have healing spells, but is a person that leans toward whacking things with a stick.
Which is your preference: attacking enemies from a distance or being up in their faces?
Are you the sneaky type or do you take pleasure ripping out internal organs as a greeting right off the bat?
He most definitely takes pleasure in whacking things in the face, or, as the case may be, in the foot.
Do you want to be on the front lines with a shield or watching over your group to keep them safe?
He likes knowing that the group is safe, but has a preference for damage over healing.
Will you be leveling with a friend or mostly on your own? If you're doing it with a friend, what are they planning to level, or have they not decided yet?
He'll be leveling with me, and I'll likely be playing either a monk healer or a paladin tank.
Have you read about classes at all yet? If so, what stands out as interesting to you? Have you tried any classes already?
No, he hasn't read about them. He refuses to listen to my descriptions, as well. Though he's leaning toward a melee character.
Are you interested in the lore or story of Warcraft? Some classes have a lot of easily-absorbed lore while others are a little "less detailed" in their history.
Interested in roleplaying at all? This goes with the previous question, but some races/classes are easier to roleplay as a newbie than others (with lots of history to adhere to).
He's definitely a lore person. Maybe not to the degree of reading quest text, as he's a terribly slow reader, but he enjoys the stories behind things.
Do any of the races stick out to you as being attractive? Not every race can be every class, so if you have an early favorite (or if you really dislike one in particular) this can narrow things down.
He finds worgen incredibly cool, which is his only preference.
