I am having trouble understanding what to do to pick these and what abilities to pick. Not sure when to use it and change? how to change? which zone? Can someone explain or give me a link that I can read about these. Also does anyone know how to get to the new zones I was doing a lot of running around trying to get to the new zones so that I could buy the new spells (port) but lots of people kept giving me bad information.

eq.crgaming.com seems to have a fair amount of information. I haven't read all of their articles yet but you may find something useful there.
