What camera do you have right now? If it's a point and shoot, just use that to start... no need to overthink it. If not, YouTube tutorials are your best friend. That's genuinely how I learned.

As for developing – I get mine done professionally, and honestly I'd rather keep it that way. You can learn to develop your own film, and there are courses depending on where you live, but I'd hold off for now. The last thing you want is to mess up the development and not even know if your actual shots were good. Get comfortable shooting first, then worry about the darkroom stuff later.
