Both are things that are not helped by having something that creates presets for you — in fact it might even be more productive to look at human made presets if you need guidence.
Also: Synthesizers are also good for creating never before heard, totally out there sounds, and those are hard to reach when you feed it existing stuff. My own personal learning approach always was to use a simple init preset and then create everything manually from there. I called this my "No-presets rule" (meaning I don't use presets that I did not make myswlf for anything, unless ot is a commercial gig). If you then make your 10th preset from scratch you probably understood something already. And then at some point looking at other people's stuff starts to make sense because now you have a set of eyeballs that can actually peeceive the things they did.
