Will, I suggest you visit concertina.net where you will get more advice and information than you thought possible on all aspects of the concertina. Alan Day (who also posts on here) has produced a tutor for anglo.

I sympathise with Ralph's "took it up by mistake". Good mistake, Ralph! I too liked the sound of the concertina (which I heard on an album, it happened to be Tony Rose playing an English) so I bought one. Like Ralphie, I was totally ignorant of the different types, or even that there were different types. The one I got turned out to be an anglo, so that's what I play.
