i use Exact Audio copy with WINE for the most accurate rip. For tagging i use MusicBrainz Picard, however Picard tags files by album release. This might not be optimal for simple file tagging with basic information
I could not get Brasero installed on my main desktop because of dependency issues. I have a test box with Kubuntu on it and I tried K3b and it works very nice. The tagging isn’t very robust, so I will be trying either EasyTag or puddletag.
I use Sound Juicer. It’s a dead simple GTK app, but it has enough tweaks to make it functional. If lame is present on your system, it supports encoding to MP3, as well as FLAC and Ogg and a few other common ones. VBR is also supported, with some quality level tweaks.
my favorite cd ripping program is asunder cd ripper which is included in the repositories of pretty much every linux distro. very easy to learn how to operate it and comes with a ton of features if you want to get more in-depth. it also does mp3, flac, ogg, aac, wave, and some not so common ones too.
