Thank you Achim and Petr for your quick replies. My apologies, but I'm quite new to statistical modeling (and the language surrounding it) as well. I'm not sure exactly what was meant by "making the model identifiable" but I think I understand the purpose...
Yes, I think this means that the factors I was looking for were in the intercept term (set to zero, for contrasts). I think the rest of my questions are "statistical" questions to do with how to interpret the model, so I will have to do a bit more reading!
