YouTube is a great resource. I follow ChrisFix and Eric the Car Guy on there. I would also recommend getting whatever the official service manual for your vehicle is. It will tell you all the correct fluids, lubricants, and torque specs to use. They usually have nice diagrams for things you might have to disassemble and put back together.
Also, be prepared to spend some money on tools. they will pay for themselves in money saved eventually but you will need to get a decent floor jack, jack stands, a torque wrench or two, and some sockets.
I've been in the process of learning how to do more work on my car too after my dealership did a sloppy job on my car the last time I brought it in for work. They spilled brake fluid on one of my headlights which ate through the clear coat and left a shop rag dangling from the right front control arm. They also put additives in the coolant I didn't ask for. I'm not going to pay top dollar to have somebody half ass the work on my car anymore or try to sneak bullshit charges in on me.
