Hi there, I've got a heap of links for you hear. I'm sure there'll be tons of other stuff but here are some tricks I wrote.
I suggest starting with the first one, it gives the system I use for memorising the chords of a scale and the reasons behind it.
I've included some links which cover some unusual chord progressions, I wouldn't call them "heavily classically inspired" but I'm guessing from the fact that you want to know about harmonic minor scales that you too have an ear for pretty violent soloing!

Enjoy!
