Try a shoe string or other string. Place it half under an old towel and slowly pull it. Most cats love playing string. Just don't leave it out for him unsupervised in case he would try to eat it or tangle himself in it.
As for the vertical space, you might need to show him that he is allowed to use them. Entice him with a toy or treat. Make sure he is watching and put some treats in different locations. Then leave the room and check later to see if they are gone.
I would keep him out of your closet for safety purposes.
