Software suggestions for Newbee

Thank you for the reply Sailor.  I was actually planning on setting my camera to RAW.  Near the end of use with my D3100 I was shooting with RAW and my plan for the new camera was to shoot in RAW and keep my files in that format and if I want to post any pictures anywhere I will convert them.

A question I have wondered is, if I shoot in RAW and then convert to jpeg, will the converted file be better than if I shot in jpeg with the camera?  Also, are all converters from RAW to jpeg the same, that is, will give the same result?
