Edit:
Sorry I didn't read your post properly, the myarmoury.com website has a wealth of information on Medieval European armour.
Osprey also produces many books for the more general and non-specialist reader. They would probably be ideal for your purposes, although I would take some of their reconstructions with a pinch of salt:

Finally there are many places where you can buy reproduction armour and weapons, although it is horrifically expensive. Check out myarmoury.com's links page.
