Please HELP I am overwhelmed!!

I live in Oklahoma and just got my medical card. I am an old woman who has smoked for a long time, even made a few good batches of brownies, but I am out of my league in a dispensary. I need a good course in the basics of how to shop and how the different strains and products (oil, wax, tincture, ect) can be used.
I am also a retired nurse who made good grades in chemistry and have known a few kitchen wizards in my day I want to delve deeply into the chemistry so that in the future I can process my own plants into the other products mentioned above.
Plants first - I have a black thumb. It's something I have worked HARD to correct since retiring. Eggplants, peppers of all kinds and roses seem to be my biggest successes so far, but this IS something I AM going to learn!!

Can anyone recommend a book they would consider All Things Marijuana for Dummies? And possible another book for Chemistry and yet another for Botany? I would prefer hard copy books. I'm old school, I want to write notes in margins, highlight portions and put tabs on the really important sections.

Any and all advice for a complete newbie would be greatly appreciated!
