Sunnats and aadaab of wudhu

Q:

1. How the khilal of the beard is done during wudhu?
2. How many times should the khilal be done according to the Sunnah?

Q: If a person forgets to read Bismillah walhamdulillah at the beginning of wudhu and remembers it during wudhu, will he get the same reward if he reads it at that time? If not, can he start wudhu again to be able to read the duaa? Or must he make a second wudhu?

Q: What is the fadhilat of standing and drinking leftover water of wudhu?

Q: When one makes wudhu, when should one recite bismillah, while washing the hands or before washing the hands? What other duas can be recited before wudhu?

Q: Is following the sequence is also a Fard in performing Wudu?

Q: If one is performing wudhu in the bathroom, and there is also a toilet in the same bathroom, then should one recite the duas of wudhu?

Q: Is it a bidah to make masah of the nape in wudhu?

Q: When we are taking wudhu, if before finishing the wudhu, we stop to talk to other people out of necessity or answering phone call for quite some time, do we have to re do the wudhu or can we just continue from where we have stopped? Please answer based on Shafii madhab.

Q: Is following the sequence is also a Fard in performing Wudu?

Q: When I make wudhu it takes too long at times as I feel I am not wetting or covering all parts of the limb I am washing. This is also causing the wastage of water. What can I do to ensure that I do not waste water and over wash? If I rub water over my arms or legs 3 times (and try to cover all areas of the arm or leg) but not every single hair gets wet will this count as still being wet and my wudhu accepted? I would say my arms and legs take the longest.
