I decided to have a look at the mission site this morning to see what NASA was saying about Endeavor and possible damage to it's underbelly. Nothing too revealing there, according to the site Endeavor's crew is preparing for a scheduled space walk with a number of goals in mind, all related to the International Space Station. The only clue that there might be concern is in the following statement: "Meanwhile, the Station-to-Shuttle Power Transfer System, which was activated after Friday’s docking, will be shut down during the spacewalk. The transfer system may allow Space Shuttle Endeavour and the STS-118 crew to stay at the station longer. A decision on a possible mission extension is expected to be made Sunday."
