ffmpeg is a free command line tool that can do this sort of thing pretty efficiently, but it aint exactly user friendly.
iTunes can do this to. In itunes, you have to set your "import" options to mp3, then for any audio track in your library, you can right click it and see an option "Create MP3 Version." If the context menu says "Create Apple Lossless version" or "Create AAC version" that means the transcoder (import options) is set to import to either the Apple lossless or AAC audio encoders. Go to iTunes > Preferences > General > Import Settings, then choose MP3 and an appropriate bitrate.

I have a Samsung YP-Z5, but it only recognizes mp3 or wav files.

you cant go wrong with mp3 @ 320 bit rate or you can go lower like 128. you cant even tell the quality difference unless you have a high end headphone with an amp and good soundcard.
that converter ryan posted should be good enough

Ya that particular converter allows you to the bit rate after conversion :cool

wtf? well that's your problem. hit CraigsList. I picked up a used 80 gb 5'th gen ipod for $80, in perfectly usable shape. I also saw a perfectly serviceable 20 gb 4'th gen for $40.

You can't raise the bitrate after conversion. mp3 is a lossy compression scheme. When you compress with mp3, you lose data. If you encode at 128kb/s, then re-encode that 128kb/s mp3 file at 320kb/s, it will only take up more space, it won't sound any better. Maybe I am misunderstanding what you are saying.

not true. the difference between 128 and 192 vbr is huge.
there are tons of free converters. go to www.download.com and search around.

When you convert from mp4 to mp3 you can chose the bit rate it converts it to.

That was the first place i went to, but the ones that worked were trial period only and limited in function unless you bought it.

Yes, I know. All encoders do that. My point was that you can't take low bitrate mpeg4 audio and make high bitrate mp3 out of it. going from 64kb/s mpeg4 audio to 320kb/s mp3 is going to give you a bigger file that sounds exactly like like the 64kb/s audio it was to begin with. Thus your maximum audio encoding quality is limited by the source, not the codec or encoding software. You can dial it down, but ya can't dial it up higher than the source.

If you are still looking, I've heard good things about dbpoweramp. I've never had a need to use it myself though. http://www.dbpoweramp.com/db-versions.htm
They say that the audio converter is part of the free package.

really? so you can notice the highs on your average ipod ear pieces between 128 and 192? i couldnt
the only time i notice is when i got my HD555 and xfi soundcard and test a song that was ripped @ 192 vs the same song ripped using FLAC. tuned my soundcard to play bitmatch
the difference was night and day :wow
yup. you are limited by the source of the song. its like taking a VHS quality video and converting it into dvd format.
you get the dvd format but only the VHS quality

Did you edit the search criteria to make sure it was free only? Hmm, keep googling around.

I can tell a big difference with $20 Phillips earbuds, or on my car stereo.
