When you hit the play button it will start playing the song you loaded in (playback bar in bottom left). What you need to do is use the tap area (also bottom left) to click on the word as it appears in the song. This will timestamp that word for that moment in the song and move to the next word - so on and so forth until all the lyrics are clicked. You can then save to import to EOF.

Best bet is to set the playback speed in the top left and then just try to be as accurate as possible but everything beyond trying to sync the word to a time is best done in EOF so focus on that imo.

The easiest way is to simply use the import / import from file within the Rocksmith DLC builder or Toolkit and select the dlc file which will let you just select the tones you wish you import.
Otherwise you can assign that tone within Rocksmith and use a similar feature to import from your Rocksmith profile which will let you access your hotkeyed tones.
Finally, if all else fails you essentially just go into tone designer and write down all the information of the tone and then create/add a new tone in the builder/toolkit and fill that same info manually.
 
Also, if you have trouble finding the ODLC file itself (the naming convention is somtimes strange) the best way I found is to go into your Steam DLC for Rocksmith, uninstall and reinstall it so that when you sort by newest that DLC will be on top.
