Yes, reading is important. If you are a writer and need to communicate to a large group and/or complicated lines to others it is the most efficienct way. The historical archive of the world's music is also in notation (not always western) and being able to read gives you vast insight into melody and also how what works and why. Feel playing is essential but beyond a certain level of basic ability so is reading. When folks are afraid of learning reading because they think it will make them a stiff player I laugh. It's just another tool to use to get your music across. Best way to learn is by doing, get a beginner's piano or bass book and work it out slowly. Also get some staff paper and write scales and rythms, then play them.
