Welcome!
You sound motivated which will get you far. Isn't it great tackling something you've always wanted to do? I'm finding such joy from playing songs that I've always loved. So my only recommendation is to have fun and keep finding songs that keep you going and trying new skills. The forums are great for asking questions, too.
