(1) Lyx is a cross-platform graphical editor that spits out LaTeX, has reasonable UI for many of the interesting things you'd do in a TeX document, and has a pretty good set of preferences and controls. I used to swear by it.
(2) LaTeX is very painful to edit in, no matter what people tell you. Yes, Word does a crappy job of typesetting. But LaTeX is very 1985. You can get similar results in a visual editor with a page layout program; this is why so many people used to rave about Framemaker over Word. On the Mac, iWork's Pages.app will do a passable job; far better than Word. I've ported Quark templates to it without a problem.
