Can I choose another location for my files?

Yes you can. Just create your own folders in a place where you have sufficient write/read permissions. You also need to add this location as a normal source in Kodi (i've read Kodi can otherwise block certain write/read access to this directory if my addon tries to write there without it being a valid source in Kodi). After this you can alter the directory locations for tv, movies and music videos in the addon settings of Youtube Library.

Will I be able to specify my NAS or an attached USB hard drive as the location for the downloads?

Any help will be greatly appreciated.
Thanks

Yes, but this is not tested by me but reported to work by others. And yes. 

 I added a folder for the TV shows on my hard drive and told Kodi it is a TV shows folder per the How To tutorial but I'm still having problems.  I've tried uninstalling and reinstalling several times.  Sometimes I get as far as searaching for Youtube videos but I can't seem to get all the way.  And it isn't consistent.  Right now I'm back to the original problem where it just takes me to the top of the menu when I try to add a new channel as a TV show.  
Any suggestions?
Thanks
