Sounds like you are on the right track, if you know that stretching is essential pre-kayak then pre-bike seems sensible. A bad back is a bad back and must be treated w/ respect regardless of the means of self propulsion.
Your LBS guy is working with you, good on that. Aches & pains are part of the process of adapting to cycling, and a consequence of doing it well.
A continuing dialogue with your fitter is in order, put miles/hours in there is no substitute.

PS
Can't hurt to research a well proven fitting system and go through all of the steps yourself.
