It’s probably a little late to answer this since the shuttle mission is done, but here are the details anyway. First spacewalk involved Michael Foreman and Robert Satcher installing a spare antenna and a bracket for ammonia lines, lubricated a grapple mechanism and a robotic arm as well as deployed the Payload Attachment System. Second one involved Foreman and Randolph Bresnik adding the GATOR bracket, a ham radio antenna, a wireless helmet video antenna, brackets for cargo, and also moving the Floating Potential Measurement unit. In the third and final spacewalk, Satcher and Bresnik installed a gas tank, deployed the MISSE, relocated shields, a foot restraint, installed insulated covers, worked on heater cables, and made preparation for STS-131′s spacewalks.
