Alright, I set up the Uno and breadboard just like on the arduino breadboard tutorial thing, and I hit Burn Bootloader. I also selected Arduino as ISP for the programmer.
It didn't work, so here is the output:
avrdude: stk500_program_enable(): protocol error, expect=0x14, resp=0x50
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
