I agree with Sweelinck, learningmodular is a great place to start learning the basics. There are some great resources on Youtube as well.

The DIY approach is definitely a good way of getting into modular, thats how I got into it when I was a student and I now design modules as my 9-5.

There are some great passive and active utility modules out there that will probably help you make your system more interactive, but perhaps you might want to look at getting some more modulation sources and filters?
