.aup and .wav files do I need to keep both of these files? and the e00 files do I need to keep these aswell?

I removed your e-mail address - it would get harvested by spambots.
You need to keep the WAV for use on your computer.
If you have a reason to save an AUP Audacity project (you probably don’t) you must not rename, move or delete the AUP file or _data folder. Do not interfere with the AU files in the _data folder.
Please see Managing Audacity Projects - Audacity Manual for more details.
It’s very likely Audacity will drop support for Tiger in the release after next.
