Hey I'm taking an EE elective and for our final project we're doing somes simple IR. We're using the Holtek H12A and H12D chips. They're relatively slow but perfectly suited for what you're doing. I just built the transmitter today and it fits on a 2x3 protoboard. The chips are pretty easy to use too.
