As another user pointed out the manual is pretty good. The tutorial is good as long as you keep in mind that it focuses a lot on keybindings, which look poorly motivated when you are a novice. However, knowing those keybindings, which are also used by GNU Readline (and hence pervasive in many text applications including most shells), is fundamental to be comfortable with Emacs. I'd personally start with a clean .emacs (or init.el) and grow it slowly as new needs arise. I've been using Emacs for more than 15 years and my .emacs is less than 100 LOC. This is partly thanks to use-package, which makes it easy to add package customizations in a controlled way. Another good resource is Mastering Emacs.
