Since you mention "more productive" I'll focus on that first. Reading the docs and example code for opensource libraries and tools I use when I get stuck, as opposed to trying to figure out how to use them myself. And using google to search for answers to question and heading to Stackoverflow if it's been answered there and reviewing all the answers offered. It's a habit now, but it took me awhile to break my previous habit of thinking I could figure stuff out without help and I'm much more productive as a result. As far as tools go, BBEdit is the one I use most.
