I'm trying to get as many mounts as I can and an idea came to me, because of battle.net wide mounts now, could you level X race to 20/40 and get the faction mounts, will it then count towards the 50/100 mount achievement on your main toon
If you don't already have them on your main, yes it will count. If you do you won't even be able to learn them.

No, you can get your ambassador title and reputation achievements.
While OP was somewhat ambiguous, I'm guessing they mean rep mounts for the opposite faction.
No, these won't count for anything if you already have the corresponding rep mounts on your main toon, and cross faction won't count towards Ambassador.
