and definitely a mask of some sort. Some form of painter's masks that will help keep the paint toxins out of your body. Most of the fellas use a 3M rated mask with replaceable filters.
Also - as far as tutorials - go to http://www.spraypaint.tv/Spacepainter which is the profile page for "Spacepainter" (Brandon McConnell)... then click on "Public Videos" and look at the videos that he has posted. There's ots of tutorials and good info there! Good luck!
