I got frustrated with it and just use TextMate. It has a latex-typeset command. It was command-B, but its command-E now I think. It integrates really well with BibTex with autocompletion of sources. I setup some nice macros to auto do certain mundane typing tasks and all-in-all I really like it.
Emacs actually has similar functionality to LyX (I don't use it, so I don't know how well it works) in preview-latex:
