For things like Google Maps it's essential. Used carefully (with regard to
bookmarking, etc. it's a bit like using frames) it can make sites much
quicker to use.

Pretty much safe to use. It's just javascript plus some asynchronous
requests to a server.

Almost all users of my sites have javascript turned on. You do need to
provide the same info, where possible, plus a message, for people who
don't. This is very easy to organise, usually.

Treat AJAX like any other javascript, that is, as a bonus rather than an
essential part of your site, and all will be fine.

It's almost always quicker than re-loading the entire web page, which is
the whole point. AJAX is a very broad term though, so the slowness would
depend on what "it" is.
