Where to start?

So I've been using my f165 for about a year and half, but not too consistently. I've made some progress and hit some rough patches as well. eating poorly at times has been my biggest draw back and seems to undo a lot of progress ive made. anyway, I got the bean this spring and have been experimenting, but i wanted to ask to get a general consensus of where newbies should start.

I know hitting worms first is the generally the way to go right? but any in particular?

then where should lyme treatment come into play?

basically what are the top things to do to start off?

Thanks guys!
