I use Foobar2000 to FLAC, but dBpowermap looks to be a decent alternative. Checked out EAC before that, but it has a really terrible interface that looks like an unintuitive design from the early 90's.
They all have questionable interfaces, except the WMA FLAC plug-in for Windows Media Player 12, but a new release of Media Player broke that a year or so ago, so if you see that option do not download it.
FLAC is lossless. From taking blind tests myself, and watching others, I don't think the vast majority, if anyone, can hear the difference between 320KB and FLAC, but disk space is cheap and you'll never question sound quality by going FLAC.
