No, not a guru by any means.... I've just killed far too many things in trying to get my thumb from black to green.
How many things?... I'll never tell!
It can be a steep learning curve and I've learned to take good notes on what I plant and what dates I start/plant them.
As the season goes on, I jot notes down on how things went and use the notes for the next season as when to plant and what varieties to plant.
I found this book to be very useful-
It does have a city/area list in the back to find your last frost date which you then use to chart everything out with. I use my own area's frost dates based on experience (not the book's) and then write up a long "to do" list based roughly on the lists and charts in the book. Keeps me focused and plugging along.
I also use info from square foot gardening methods, which is intensive planting in wide blocky rows. Which you can co-plant hings together and often through out the season for fall harvest too.
And apparently, I can't type or spell very well after 10:00pm my time as clearly outlined in my first post.
