WAV to MP3?
As pretty much everyone knows, encoding an MP3 to an MP3 will cause a noticeable drop in quality. Now, I've been renting CDs from my library and ripping them to my computer in MP3 format (with EAC/LAME) and keeping WAV files in data CDs. Say I decide to convert one of the WAV files to MP3, will there be any noticeable loss, or will it be exactly like ripping from a CD?
Also, burning MP3s to a CD and then ripping the CD to MP3 files will have a huge SQ loss, correct?

Big no-no on the second question.(actually you answered that in your first sentence)

They will (or at least should) be exactly as if you ripped from the CD and encoded directly to MP3.
Burning MP3s to a CD and then ripping the CD to MP3 files is a big no-no. Just as bad as transcoding MP3 to MP3..

Try and hear for yourself.
I need mp3->wav->mp3 when recording a speech on a DAP, then processing it on a PC, encoding to low quality mp3 and posting it on teh intartubes.
Btw there is no difference between CD->mp3 and wav->mp3 because in fact when ripping a CD it is actually saved to wav first, then encoded to mp3. If you use a good ripper (EAC), you should get an accurate wav from your CDs

Renting? You mean instead of borrowing, your library charges you, which then makes it OK to make copies (wink wink)?

Regarding the second point - you won't degrade your MP3's (any further) by putting them on to a CD. Just don't transcode them again to a lossy format, just copy 'as is' to a suitable MP3 device or music library. Most of the original wav file inofrmation is lost by this stage, but you don't need to lose any more.
I realise I may have missed the point somewhere along the line though...

Right, right of course!
Thanks for the responses everyone, I figured the quality loss regarding the second question was obvious, but I'm glad to know that I can just keep wavs in case I want to re-encode.
