If you want to learn more basic concepts, I'd recommend looking perhaps for a class in your area to audit, or possibly mit ocw might have something.
I will say the following though:
1) many folks in industry get to a point to where they rarely, if not never sit down on paper and do node-voltage analysis. They eventually get a conceptual "feel" for everything and work in simulation environments (matlab, spice, etc.). The best way to get here is to do the conceptual exercises on paper first, then play with a simulator afterwards.
2) designing basic analog circuits can be learned from textbooks, but doing more "active" things like building a switching power supply requires more specific books.
In later classes we used this book, which I see in the bookshelves of my coworkers: http://www.amazon.com/Microelectronic-Circuits-Electrical-Co...
