Unfortunately, the only way to keep him still is to confine him. You can do so by putting him in a dog crate or other cage to keep him still.
For the paw, you can flush it with peroxide and then apply some neosporin. Some cats will allow you to slip a baby sock over the foot and tape it loosely at the ankle.
But some won't. With these cats, you need to get an elizabethan collar from your vet. It looks like a lamp shade and will restrict her acces to the sore.
If it's still bleeding after all this time, she may need a stitch to get it stopped.
Let me know if you still have questions.
