Before you even figure out why you say "on belay," you'll need everything in Edelrid's Zack Harness Starter Set Package. This starter set includes a climbing harness, belay device, locking carabiner, and chalk bag to ready you for route climbing class. Now all you need are shoes, a rope, and a buddy to belay. The Zack Harness has plenty of padding and mesh to keep you comfy as you get comfy with heights, and adjustments at the waist and leg loops assure a secure fit when you're hanging up there. There's an abrasion protector at the tie-in points to reinforce your assurances even more. The Jul Sport Belay Device has ridges on one side to add friction to climbing ropes, something that really comes in handy when you're learning how to belay. Just make sure the Nugget Screw Locking Carabiner is locked after you load the rope, and then say, "on belay."
