Welcome along! That'll be a nice little setup there, I'd recommend getting WHDLoad to install those floppies on a hard drive / flash card and save a lot of waiting for things to load
Blitz shouldn't be too tricky to get running anywhere - it ran first go on my A1200/030, a WinUAE setup, and under OS4... And it's even developed under UAE. You could post a message on the forum at amiforce.de if you need help, they're very helpful over there
