What are the sizes to expect for audio files?

I am starting a home project to convert all my tapes into music CD's.  I am using Creative Wave Studio for doing the recording, WAV-MP3 Converter Recorder to create MP3 files for long-term digital storage, and Burn4Free to create Music Cd's in CDA format.  The WAVE files are recorded at 44100Hz 16 bit Stereo with PCM compression.

I recorded one side of a tape (Bruce Springstien, Born In The USA) and the one-piece wave file was 248MB.  The first song when I cut it out was a 48MB wave file.  I converted that to a 4MB MP3 file.  

Are these the file sizes I can expect?  They seem awfully large.  What is the normal Hz for most MP3 files or purchased CD's?  Can I reduce any of those settings without losing too much quality?   What is the file size I can expect when I convert the wave files into CDA to make the music CD's?

Thanks all ... Kirk

Simple answer yes.

A standard music CD can contain 650 Mb of music which is 72 minutes of music.

So, roughly, that's 9 Mb of data per 1 minute of music.

When you go to MP3 you get about 10% of the size which is what you are doing.

Generally you do the compression for MP3s at 128 kbps

This is reasonable, about FM radio quality or slightly better.

Now, cough, you don't convert the wave files into CDA.  The CDA is just a pointer to a wave file on the CD.  The wave files get copied over to the CD, so a 248 Mb wave file you have gets copied over to become a 248 Mb wave file on the CD.  And you end up with a small CDA file as well on the CD.  I think it doesn't go past 40 bytes on size (and that may be too big).
