Just do it. There is no other way. You have to build a relationship with Music. It doesn't matter what instrument you play, it can be all of them or none of them, but an instrument doesn't teach you about Music. Instruments are just different ways of bringing forth Music. You don't need theory unless that is the level you are intending to communicate on. Tons of bands get by with only the slightest of knowledge of theory. It's useful if you are communicating a lot with other musicians but as a solo composer it's barely necessary.
I would however agree that keyboard/piano is probably one of the best ways to build a relationship with Music because of how it is laid out and because of the range of frequency that is in it. Really easy to build an understanding of how the notes work together. I find it's less important to be able to specifically name chords so much as to be able to identify the major intervals (2nd, 3rd, 4th, 5th, etc) and beginning to understand what kind of emotion is created through those chords. Consonance and dissonance come a lot from this understanding of the ratios of frequencies, but you don't need to know the math, you just have to listen for what you want.
Get a metronome and learn to count. It doesn't matter how fancy your rhythms or chords are if you have no timing, there will be no proper flow. If you can master timing then most of the other elements of music tend to fall in place behind it.
Also, you don't need a lot to do full recordings. I'm a solo composer and I do multi-tracking to record my own full tracks. Just bought an electric drumkit off my co-worker so I can finally start recording my own drums and samples, now I just need a bass and I can do the whole band. At one point I had nothing but a webcam microphone and I still managed to make some crappy demos.
