Do you mean Real Contact instead of Full Contact? Full contact stick fighting means you're covered in padding, but fight with naked sticks. You'll still get plenty bruised, especially if you use heavier sticks. Real contact is what the Dog Brothers do, and you should probably be pretty comfortable sparring before you start with that.
I'd recommend starting with padded sticks like Smak-Stiks (which are pretty soft) and then maybe moving to Lameco sticks, which are padded rattan before going to actual rattan. Once you get to rattan you'll want a fencing helment, hockey gloves or the like, and probably elbow and/or knee pads.
As War Wheel said, don't do this if you can't afford to get injured. I've gotten plenty bruised wearing full WEKAF gear.
