I've been very happy with dbPoweramp. http://www.dbpoweramp.com/ I've used it for years. There used to be a free version, but I'm not sure it's free anymore. I paid for it long ago, worth every penny.
I like MediaMonkey for organizing my files and cleaning up the tags (including adding cover art). http://www.mediamonkey.com/ The free version rips CDs at only 4X speed. If you purchase the gold version, you'll get fast ripping, and I would then skip dbpoweramp.
