Freedome of the Hills is "the Bible" of mountaineering, but it's kind of like a children's Bible. Good pictures and you get the point, but if you want to get serious about it you'll be left wanting more. I guess I just look at my bookcase and FotH is surrounding by other books that cover the same topics in more depth. If you're looking to save money, I'd start with skipping FotH. I'd recommend Michael Layton's Climbing Beyond the Basics as an overview book that isn't too broad to be useful.
I took a trad anchors class at J Tree that was great https://www.joshuatreerockclimbing.com/sem4.html. I also have a friend who's an single-pitch rock instructor in Northern California. If you're interested, I'll send you his info.
My crevasse rescue class with Rainier Mountaineering was great. My "Mountaineering Class" with RMI was a waste of time and money. All classes are good, but specific well-tailored classes are well worth the money. In Cali, there are some great resources. Sierra Mountain Guides is a fantastic company based out of Bishop.
Classes may seem expensive, but the amount you'll learn (especially if you prepare beforehand) is fantastic. Also, you'll be trusting your life to your skills - probably worth the extra few $100 bucks
