3rd step would not be concerted. Although I understand lack of proton transfers for simplicity's sake, and you mention that there are several potential inaccuracies... but the general idea is there. Much applaud, better living through mechanisms.

If you're interested in learning a bit more about mechanisms specifically, which can be very relevant to understanding protein functions in a biological setting, a favorite of mine is "The Art of Writing Reasonable Organic Reaction Mechanisms" (https://www.amazon.com/Writing-Reasonable-Organic-Reaction-Mechanisms/dp/1441930167, http://jpkc.huanghuai.edu.cn/include/htmleditor/uploadfile/20130309151535265001.pdf) It has straightforward explanations of the basics in understanding many of the core concepts relevant to mechanisms and is a popular read for undergrads and grads alike. Each chapter has exercises at the end and the answer key is free online (http://www.springer.com/us/book/9780387954684).
