If you are using the GNOME version of Mint, you already have Rhythmbox installed. Rhythmbox will rip and encode a CD. I think it rips the entire CD at one time. I currently use Sound Juicer, which is available via Synaptic. I can pick and choose which tracks I want to rip and encode. I have used both Rhythmbox and Sound Juicer. Those are the GNOME options I have used and can suggest. In KDE, I have used K3b to accomplish the same tasks. Maybe that will point you in the right direction. Have fun.
