Reply to korg nano,traktor and itunes

I havnt been on this site long but I want to thank everyone that contributes to it,I believe its amazing what you are doing for the community and your help is much appreciated by myself. Right to the questions.

Would it be possible to map the xy pad on the korg nanopad to the track search function and use it to scratch?

Can I drag and drop music from within itunes straight into a deck within tracktor?if so how because I havnt had any look so far.

Last question is, is it possible to have playlist within playlists in itunes?I have a playlis called djmusic music with all my tracks but I would like to put these into genres but keep them within this playlist.

Any help would b great thankyou.
