Well there's always value to have protection... but I think for you since you have 2 clear cut number 1's I wouldn't worry too much about Bernier or Thomas since you don't have Quick or Rask... The main reason why you would pick up one of those guys is so you get all the starts from a team.
What I might look at and seriously consider is picking up Chris Osgood since you have Howard... if howard gets injured or tanks you have the protection of Osgood to ensure you get all the starts from the Red Wings.
