I had the feats bookmarked and handy - here ya go.
To my knowledge, all the web enhancements (including the spells you mentioned, magic items, and prestige classes) are available from the My Downloads tab at the top-right of the page. (Actually, looking now, I only seem to have the latter two. So I guess I can't help you there.)
There's also Pathfinder OGC, which has all the beta stuff compiled and sorted kind of like d20srd.org and whatnot, with the caveat of being a website and not a PDF of course.
