Jim, a respirator or dust mask is essential. There's little to no need to protect your eyes and ears, if your not going to protect your lungs. It's the dust that you make that will kill you, so, you have to protect your lungs from inhaling it. Before you buy any more tools, you should buy a dust collection system. It's not who owns the most tools that wins, it's those who protects themselves from inhaling wood dust that wins. I own all of the tools that you own, and even more. What I put the most value on, is my dust collection system. I still have to purchase an air filtration unit that hangs from the ceiling, I plan to do that this summer.
