You should at least get your own mask first- that's what you'll need to use every time you play.
Ben has a few of these Dye i3 pros for sale at the field and some JT proflex- I am using the JT proflex- he has Red Blue and Yellow.
With your own mask you don't have to use the rental masks which can get oily and smelly, scratched lenses sometimes fog up.
Gloves- to protect your fingers esp on the phalanges (between the knuckles) which will hurt like hell and be sore for a long time. I hate getting hit in the fingers more than any where because every time you put your hand into your pockets.. you'd feel it.
And to protect your palms when you slide or dive into the bunkers.
