Is there any way to copy the same track to the same CD in uncompressed wav, 192kbs, 256kbs and 320kbs formats? This would allow me to easily switch between the different encoding to see if I can tell the difference on my primary music system.

If It can be done, can I use EAC/LAME to do it and how can I do it?

You should turn the various MP3 files back into WAVs (this simulates their playback by a decoder), and then get a friend to burn the test WAVs plus the original WAV to a CD but get him or her to randomise the order (recording it somewhere you can't see). Then do the tests with the friend absent and, only when you've evaluated the various tracks to your satisfaction, go and find out which was which.

Possibly you could find a program to take the rather thankless part of the "friend", but I couldn't immediately find one: WinABX and friends emit their tests out of your PC's sound card, not onto an audio CD.
