I have found a very nice tool called "abcde". It is a tool for cd ripping and encoding. It's not a graphical tool, but a command line tool - a script actually - but it is not difficult to use - it's very easy. It does averyting for you. Just put the cd in the tray, launc a console window, write abcde, ansver a couple of simple questions, and then it do everything for you. Very effective and simple. I don't know if it's in Ubuntus resopitories. I picked mine from Debians testing.
Good luck
