idiot buys a few modules and hopes for the best - Help

I know i want to get into modular and just bought a few random things as below. I want to get some self generated but adjustable melody going a basic drum beat. I then want to be able to play around wit hAudio clips through the system. I've ordered a Radio Music from Music Thing Modular but what else is the current favourite / should i get for beats, melody and sound manipulation?

Just ignore if fed up with newbies as there seem to be a huge and growing number!

Here i what i've bought on a whim so far....

I think a Beatstep Pro would be a good addition for sequencing everything and melodies, you probably already know the O-Coast has midi and cool midi functionalities.
