Rayburn is right...the answer depends on what you build and how you build and so on.
I might be able to offer a few tips though:
Consider having several work benches...one where you paint, another where you carve, and a third where you do things like insert the lips and screw eyes, apply the epoxy finish, etc.
You cannot have too many lights in your work areas. On my "finishing" bench, where I apply epoxy, insert diving lips and screws, I have four lights. Its like Yankee stadium when I fire them up, but I'll tell you what, if I fail to use even one of them I notice the difference. Light is your friend. Light is good.
Like Rayburn said, try to keep everything within arms reach of your painting bench and your finishing bench. Your carving/woodworking bench should have no trip hazards in the work area.
Keep eye, ear and lung protection (respirator) in use and maintained AT ALL TIMES. SPEND THE MONEY AND BUY THE STUFF NOW!. This is a hobby full of potentially dangerous, abrasive, toxic, nauseating things, including chemicals, dust, and finger-eating power tools. Use proper ventilation. Maintain your power tools: replace worn out parts and use sharp blades, bits, etc. Safety first at all times
