Any suggestions on my next steps or purchases?

Try to build things you're interested in. ;-) If you need tools, get 'em.
If you're not sure of each & every step, ask for help and/or take a class.

If you need ideas, I built a bunch of small boxes from 1/4" hardboard. They
hold my glue bottles, small tools, etc. It was a good learning experience
to make them come out square. ;-)
