Visiting Madina Munawwarah

Conveying salaams to Nabi (sallallahu alaihi wasallam) from anywhere in the Masjid

Q: 

1. When in Madina Munawwarah, can a person give Salaam to Nabi صلى الله عليه وسلم from anywhere in Masjid Nabawi? 

2. Can the above action also be done while sitting outside the Masjid while at the qibla wall side? 

3. Can salaam also be given to Abu Bakr and Umar رضي الله عنهما from these place or is it only possible when directly in front of the Qabrs?

Women visiting the mubaarak grave of Rasulullah (sallallahu alaihi wasallam)

Q: I have a question regarding visiting the Raudhah (the blessed grave of Nabi (sallallahu alaihi wasallam)) as the workers here have created a doubt in my mind.

A staff member was explaining that when we (ladies) visit the Raudhah, our intention should purely be ibaadah in Riyaadhul Jannah and not to visit Rasulullah (sallallahu alaihi wasallam) as he disliked ladies visiting graveyards. Then she quoted an aayah or Hadith in Arabic and stated that Nabi (sallallahu alaihi wasallam) did not make an exception for ladies to visit his grave. So she mentioned that we should all rectify our intentions before going inside.

Is it correct for women to make the intention that they are visiting the grave of Rasulullah (sallallahu alaihi wasallam)?

Woman beautifying herself before visiting the Mubaarak grave of Rasulullah (sallallahu alaihi wasallam)

Q: Recently a woman told us that when you go for hajj and go to Madina Munawwarah to visit the grave of the Holy Prophet (sallallahu alaihi wasallam), a woman should wear new green clothes, perfume, bangles, henna and apply red colored pigment (called gandasa) on her lips. Is it all true or bidah?

Also, is it necessary to make new clothes or wearing white clothes for hajj for a woman?
