There is an option for stance (form is shorthand---same thing).
/cast [stance:1] SuperDPS; [stance:2] SuperHeal; [stance:5] RunAway; [form:3] TankyTankSpell

Info: http://www.wowwiki.com/Stance

Also remember that no goes with anything, so [nostance] [noform] might help sometimes. Also, like you said, you can just check for stealth. [stealth] [nostealth]

I am 98% sure that the < lvl 6 starting quests are race specific. But anything >6 is open for everyone. You spend 10-30 mins depending on race choice going from place to place (BE > tauren being long, tauren >orc/troll and undead <> BE being short). That 30 mins investment is nothing when you are talking about weeks of play to get them leveled. Pick what you want and do it, don't worry about what you have to do to get it.

Pick what you want, not just what others tell you. You will be the one playing these chars for a LONG time. Pick ones you want to play. Again, I would choose based on what you want to do with them. Think about BGs, WG (new WG areas in Cata), instancing, group quests (not a lot of those now), grouping with others (not a boxer's style, but still can be done), world PVP (if on a PVP server), speed of killing, safety of killing, can you both have escape mechanisms, etc.
