Answer 1

Series 3 is going to start at the end of October check here: http://en.wikipedia.org/wiki/List_of_Gavin_and_Stacey_episodes#Series_Three_.282009.29

No its 26th November


Series 3 actually starts on 26th November on BBC1, which was confirmed

Answer 2

am afraid that it does not look like there will be one as joanna page , Larry lamb, James corden and Ruth Jones have all said that series 3 was the last but as Larry lamb commented he thinks you will see more of gavin and Stacey because he thinks they will do chrismas speacil and if they do this may encourge them to do more series
