I always take ALTTP to be last, because it's the only game (that I've played) where Link gets the full Triforce. I take this to mean Link's wishes all come true, Peace in Hyrule forever and Link's evil fighting days being over. I'm stickin LA sometime before that, as release date is irrelevant to the timeline (OOT was like the 5th game wasn't it? but most say it's the first in the timeline) and sticking LA there adds a little bit of creedence to my "Dream" idea.
