I use EAC to rip to FLAC but I know it works admirably with the LAME dll/exe (I forget which). EAC holds advantage over many rippers in that it has 'secure rip' support, I had issues with certain other software ripping the next second of some songs into my current one until someone here pointed me towards EAC, haven't had that issue since (or any for that matter)! It doesn't rip to MP3 out the box but when set up properly it works like a dream.
For playback if I'm at the PC I use foobar2000 which looks bland until you throw in Columns UI. If I'm not sitting at the PC I use XBMC as it's the best media centre I've found.
