To help with the playlist side of things... i use itunes to organise my playlists and import the ones i want via the itunes node.... import as playlist by right clicking the folder i want from within the itunes node.
if you have folders full of music on your mac representing genre - get them in to itunes..
the easy way would be to ensure you tick the box 'copy to itunes folder' within the itunes preferences..
then make a folder for each genre to mimic your folders on the mac inside itunes (these are called playlists).. then drag / drop each of the files within each of the folders on the mac to the playlists you have created...
Then go back into traktor and open the itunes node - you may need to specify where the itunes folder is located in the traktor preferences first.
The other way would be to bypass itunes and copy your music directly into traktor - same sort of thing here, each folder by genre will be created when you drag folders under the playlist node...
As i use rekordbox & traktor i find using itune as the central point to organise my music is easiest - shame rekrodbox doesnt update each playlist automatically.. maybe in time eh!
My cables are usb to the mac for traktor + ethernet for prolink via a 5 port hub to the cdj2k's - its messy so i only use rekrodbox and prolink most of the times...
