Ripping music questions

[Silent Ph03nix]

Ok, I recently bought a 500GB external HD (firewire, but also capable of
USB) to rip all my and my wife's CDs onto.  So, I'm going to rip them
preferably to FLAC (or possibly wav if necessary) so I have lossless
copies of the CDs that if the CD ever gets scratched or lost or
whatever, I can just re-create the CD at original quality.  Ok.  That's
easy enough.  What I have questions about is taking those files, either
FLAC or WAV and converting them to OGG and MP3 formats.  Yes, I have to
have MP3 as both my and my wife's car stereos only play MP3, not OGG and
we're not replacing them, not to mention the portable MP3 players my
wife and daughter have that they aren't replacing (mine plays OGGs). 
What I want to know is how do I convert these files while keeping and/or
creating the ID3 tags for the .mp3 files as well.  I prefer to have
complete and accurate ID3 tags on all my files so they appear correctly
in the car stereos etc.  What's the easiest way to accomplish this?

Thanks in advance,
