Is it possible to setup a hardware interrupt to trigger from for example PA3 & PB3? If so, how does the interrupt handler determine which one has triggered?

No, see RM0360 chapter ''External and internal interrupt/event line mapping'' (chapter 11.2.5 in rev.1).

You could work around this by using an interrupt from timer capture, if some of the pin maps to an (unused) timer channel.
