And this is one of the biggest mistakes I saw - Edit 1

This is why Nynaeve found Rand's short-hop trick "clever." Say A is starting point, B is close to A, and C is the destination (far away). If one doesn't know A well, one can Travel from A to B (short distances for Traveling are easy). The act of Traveling to a location makes that location well enough known to travel from it. As a result, after Traveling to B, you can Travel anywhere you'd like (i.e. C).
I don't know how many days have passed since Nynaeve took Lan to Land's End, but it can't be that long ago, time-wise. Anyway, Nynaeve used this very "trick" to drop him off and then go round up recruits. In fact, there was a reply from RJ himself in his blog, because so many people had asked about it:
"For several people. Nynaeve could Travel after depositing Lan in Saldaea because she had “learned” that spot by Traveling to it. Remember, if someone Travels to a place, they now know the place they have Traveled to as well as if they had spent time there learning it." Dec. 2005 blog entry
So, either Sanderson messed up, or, Nynaeve doesn't know squat about Travelling, or, she's been smoking some of her "herbs".
