Sunnats and aadaab of wudhu

Q: Please let me know all sunnah and mustahab duas that should be read during each step of wudhu. The dua while washing hands, gargling, cleaning the nose and so on till washing the feet.

Q: What is the preferred method of making khilaal of the toes?

Q: I came to know about the hadith of Nabi Muhammad (sallallahu alaihi wasallam) that wudhu is not proper if we don't say Allah's name before wudhu. I didn't know about this. So I mostly made wudhu without saying Allah's name. Was my wudhu accepted and am I sinful?

Q: When should khilaal of the fingers be made in wudhu? Should it be made after washing the arms till the elbows or after making masah of the head?

Q: I just got 4 of my wisdom teeth removed and my gums are in pain and constantly bleeding. If I rinse my mouth a bunch of blood comes out. So how do I make wudhu, and how do I pray?

Q: Should the dried pus on a pimple be removed during wudhu and ghusal?

Q: In the process of wudhu, there are 4 fardhs; washing the face, the arms, masah of the head and washing the feet. Kindly clear my doubt if washing of the face comprises of gargling the mouth and cleaning the nose.

Q: Does permanent ink affect the validity of wudhu and ghusal?

Q: When I was doing wudhu for fajr, I checked my eyes for any dirt in the sides, and found some in my left eye, so I cleaned it and rubbed both eyes. But after I finished fajr prayer, I found some dirt besides the right eye. I had not seen this dirt during wudhu. The dirt was dry and 3mm thick. Will my Salaah and wudhu be valid?

Q: Is my ghusal and wudhu valid if I dye my hair? Is my salah valid?
