Get a good respirator and plan on living in it, you can skimp out on all of the tools and materials on the list, but you only have one set of lungs. Polyester resin is pretty toxic on its own, but when you get to the sanding I still wouldn't trust just a dust mask. You're going to be making a lot of fine powder and getting glass in your lungs is not good.
Eyewear, I wore safety glasses for the sanding and cutting, but a pair of goggles would be a wise investment, the fumes from the resin can cause burning.
Gloves and long sleeves, getting any of this on your skin can cause burns.
