Patch & Tweak is also a great source.
I also went my own way (after a couple of months / years... doesn't everyone?), more or less... but did ask for and get some hard (good) advice... that I kind of listened to (Utilities, Star mults, VCAs, that damn big(ish) but really useful matrix mixer ;)).
Every use case and user is unique when it comes to creating things... modular makes it way more complicated with the vast options it offers to the creators (which is one reason why it's often recommended to start with a simi-modular)... but the foundation is the same...
"In order to get sound out of your modular and have a working instrument, you must have the following things purchased:
Case / Power Supply
Oscillator or Sound Source
Modulation Source
Sequencer
VCA"
Start here... maybe add an multi FX module... these 4-5 simple things (or complicated if you want) and then learn from there.
