I've never found any S4S lumber purchased to be consistent in thickness or available in a finished width that is straight or ready for glue up to make a wider panel. Considering your collection as a power tool user, at minimal you might want to consider a bandsaw, a portable surface planer and a small dust collector. All of these could store in a few square feet. Next suggestion would be acquisition of a long bed jointer because even though your router table has some capability of joining an edge, you're in need of a method to flatten the face of the stock to remove bow, cup or twist.
