Another vote for http://www.largeformatphotography.info/ articles and the active LF forum at http://www.largeformatphotography.info/forum/ - there are many APUGers there, too. If you like books, I'd suggest a browse through Steve Simmons "Using the View Camera".

Personally, I would also suggest you consider a 4x5 if LF is your goal. Above all, welcome to the world of LF, once in, you won't let go...
