How can Obama give a speech on what is happening in Libya?

Simple, the USA is providing the Radar and Satellite intel, therefor it is forwarded to his staff as well as to the other nations involved. Most people don't realize that Air Force One has all the capability of an AWAC plane as well as even more satellite communications. so President Obama is probably more able to know what is going on from Air Force One than any local commander in the field in Libya.
