A kitten,is a kitten,is a kitten,I would suggest another little kitten to keep him company
Double the fun..and they will chew on each other rather than your feet.
Anything dangling,cords etc..is a toy to him,is not only expensive to replace,but can also be a killer to kittens.
Like Badger says,this behaviour will change as he gets older,at 8 weeks,he is just a little furball of play.
Discouraging him from climbing your back or legs by putting him down,no yelling or hitting,will eventually make him understand.
