There are few minor things that Traktor does differently to iTunes for e.g. write tags in ID3v2.4 whereas iTunes only handles ID3v2.3. So I save my tags in 2.3 and as soon as I play them in Traktor there converted to 2.4. I did save them in 2.4 BUT win 7 does not support them so i reverted back.
I say this because iTunes is where I do ALL of my organising, smart playlists, playlist etc. but read this thread carefully. Hope it helps.
Any further questions you have you can start a new thread and I can answer them over there.
I also have a beatport script you might be interested in here.
You can't mail me? I've received mails recently. 
But as I said start up a new thread and I'll get a notification of any new ones so you wont go unnoticed
