Istinja after relieving oneself

Q: When I go to the toilet, I find it hard to wash my hands. I soap them then put them under the tap. Once all the soap is off I think the water on my wrist is impure still so I wash my arm from the elbow to finger tips and I keep doing that and still I have a feeling that my hands are impure even if I've urinated or past stool still I wash my hands like this and I use wet toilet paper 3 times instead of istinja.

Khilaal of the toes

Q: Regarding khilaal of the toes, should one make khilaal of the toes of both feet together after washing both the feet or should one make khilal of the toes of the right foot after washing the right foot and of the left foot after washing the left foot? What is the sunnah method?
