Method of ascending the mimbar?

Q: Is there a sunnah or recommended method of ascending the mimbar? Because I see some people ascend each step with their right foot and then turn around on the last step, while others walk up with both left and right feet, and still others walk up backwards. So has the `ulama mentioned anything in this regard?

Doubting if one read a Surah after Surah Faatiha

Q: If in a two rakat prayer one doubts in the second rakat whether one had read a surah after surah al Fatiha in the first rakat, should he read in the second rakat after surah Fatiha 2 surahs? What should he do in a 4 rakat prayer? If he is sure that it is left out, is it waajib that he should read it i.e. in a 4 rakat prayer should he read it in the 3rd rakat or can he leave it out and do only sajdah sahw?

Making niyyat for leading women in Salaah

Q: I know that it is necessary for the Imam to make in intention for leading the females in a congregation. However, what is the ruling if initially the congregation is all males, but then a female joins afterwards? Will the Imam have to change is intention in mid-prayer? Also, what if the imam never finds out that a female has joined the congregation (since he can't turn around), will the females prayer be valid?
