The tracker interface has probably the highest learning curve of any "standard" method of making music digitally. There's a lot of tradition behind it, it's a really weird paradigm honestly, and as someone for whom it's sort of a primary method, I don't recommend it unless you're aware that it will be a significant time commitment, there are some pretty big limitations to it, and you may never succeed in actually feeling comfortable with the interface. I would say there are only a handful of people in the world who have truly mastered the art of the tracker. The rest of us sort of hobble along behind them.

• Find some tutorials and watch them. Go all the way through a bunch of tutorials with the program closed, just to get the feel for how someone might approach problem-solving with this tool. Once you're done, start over with the program open and follow along.
  
• Download other people's modules and tear them apart. It looks like you're already doing this, which is good. But go further. Slow everything way down, play around with effect commands, try to see how a certain sound was produced and how you can replicate it. I did this a lot with Virt's old stuff, as he was the one who inspired me to pick it up in the first place.
  
• It can be helpful if you plan your song in advance so you have less problem-solving to do in the tracker itself. I neglect this most of the time, and as a result I take a long time to finish anything.
  
• Do not be afraid to experiment. Your stuff will sound awful for a while. That's okay. Come up with an artist name for awful stuff, or release it anonymously. Do better next time.
  
• Be always on the lookout for samples. Find stuff that sounds good, save it, and keep looking.
  
• Don't think, feel.

Back in the day I used to like following the Soundevotion Competition. They always had some pretty good samplepacks. All the entries are in Renoise format, so you'll have to use a different program to read them, but it's a pretty big database of both samples and techniques, ranked somewhat by module quality. Renoise is commercial, but it's free to try; you just can't directly export to wav (although there are ways around that).
