planning the garden with non-hybrid seeds

Time to plan the garden!  I've received so many seed catalogues, I don't know what to do with them all.  I have saved seeds in the past from my plants (from non-hybrid plants).  I think with the way the world is going, I will start saving more this year.  I wonder if the non-hybrid seeds will grow better plants.  Will the non-hybrid seeds stored last a long time?
