Got another question. I'm using this guide: http://accomp.me/ffxiv/monk-and-pugilist-fists-of-fury/ , to figure out more about monk and pugilist stuff. It talks about abilities necessary for monk, and now I'm afraid without knowing what I'm doing I'm going to mess something up. So my question is...

Since I'm going to be a Monk, I'll be a level 30 Pugilist, and a level 15 Lancer. I remember someone before (think it was Clavaat guy), saying that I'd get skills from Lancer and Marauder as Cross Class Abilities for Monk, and a Pugilist can have 10 from any class. So I guess now I have 3 questions. If say I have an ability crossed over from a Gladiator class for my Pugilist, does that mean my Monk can't use them? And secondly, are there some must have skills or good ones I should cross over for both Pugilist and Monk? And once I become a Monk, what are the odds that I'll be switching between different classes, because from what I'm hearing Monk is just gonna be better.
