Honestly I do think your email is a little too much.  You are asking a crap load of questions that really would put me off if I was the breeder for the first time I ever heard from you.  I'm not saying you should never ask those questions but I think many of them should come up in conversation or after you email each other a couple of times.  Your email does give the feel of being bombarded and getting the third degree all at once and it probably would put me more on the defensive myself.  I actually think the breeder was pretty polite to you other than the snarky response of asking if she passed the exam.
