Seems like all your questions have been answered by the helpful folks here, but allow me to chime in!
That’ll come in handy when you start buying your flying training. It can get pretty expensive, and the higher the reputation you have with a faction, the cheaper their prices are!
As for cool looking mounts, you’re a troll mon! You’ve got access to the sportscars of racial mounts - the Raptor. You can purchase them from Sen’jin Village in Durotar. They come in different flavours too, so go nuts.
You can also purchase mounts from the Auction House if you’ve got the gold handy. There’s a few cheap ones on there.
Unfortunately if you’re looking forward to flying you’re about to learn the downsides to “Pathfinder”. You’ll be able to fly in most early zones up to level 90 once you hit Draenor - that’s when Pathfinder was introduced, and flying will be locked until you complete it, which can take a very, very, very long time. You’ll enjoy Pandaria though (level 80). It’s breathtaking (I can’t help but think of Keanu everytime I hear that).
A tip I wish I knew when I started, if you haven’t already figured it out… if you get stuck and feel like you’re wasting time wondering around, go check the mission board in Orgrimmar. It’ll list a few starting points for the level you’re currently on, and then you can follow the quest breadcrumbs from there.
Wowhead is probably the best resource when it comes to WoW. It saves my butt every day, well, the comments do anyway. Always read the comment section, because the people there are incredibly helpful and will often already answered the questions plaguing your mind when you went there.
If all else fails, you can always come back here. There’s always someone around to lend a hand. But yeah, I won’t lie, the game can feel a little anti-social at times. I’ve levelled a few characters to 120 without speaking to a single person…
