Andy,
Glad you got it going well!
You can lube the kybd in place. Never remove a kybd without the E rings in place.
Remove the main cover and then the little E rings and maybe a washer on both sides of the kybd cover. Gently pry the frame away from the kybd cover on each side in turn and remove the cover. Clean all the cover holes with 409 on a rag and using your finger to reach inside each hole.
Then lube the two black shafts on each side of the kybd with lightweight oil. See pic. Separate the nylon swivels carefully to lube the whole shaft. Replace the kybd cover by gently prying the side frames in turn to install the cover.
Cleaning the kybd cover holes and lubing the two black shafts will help to make the kybd touch better.
As to the cover stickers the paper ones can be soaked in water overnight and should come off with razor blade scraper used very carefully. The metal one is another matter. Best to leave it on unless you think it can peel off in one piece.
Also the WU dial logo can be removed but its ugly under the decal so best to leave that one in place.
Hope this helps.
