Excellent guide. May want to add to add to the level gap thing that not only is it important to keep the gap close, it's also generally important to try to have the tanks and DDs as the highest levels in the party as opposed to the healers and support jobs, since healers and support jobs don't take as big of a hit to their performance for being underlevelled.

But what I REALLY think should be included is "Don't overhunt." Waaaaay too many people do it, even those that know how to play properly and lead a party. I guess that could go under "Know what you're going to kill" if you don't want to add an extra bullet just for that.
