Reciting Surah Faatihah behind the imaam

Q: My question is regarding the method of jamaat namaz:

1. If someone is offering namaaz with jamaat, should he be required to recite “Surah-fatiha” and a surah after that if the imam is reciting it?

2. Now in the case of Zuhr and Asr prayers (when imam is not reciting loudly Surah fatiha and Surah) do the people have to recite it or should they simply stand quiet?

3. In the last 2 rakats of a farz namaaz, I know that surahs are not recited after surah fatiha, I just want to confirm this from you?

4. If I join the jamaat in the rukooh of the first rakaat, I don’t need to repeat the 1st rakaat (this is what I understand); now when will I recite the thana “subhanakaALLAH...” ?

Clean shaven Qaaris

Q: The norm today is to employ famous clean shaven Qaaris to entertain the crowds. Some Ulamaa say the idea is to promote and encourage the youth to learn and recite the Quraan. Is it permissible?

Is it permissible to allow photo's and videos to be taken in the Masjid while the Qaari is reciting. Shouldn't this entertainment be conducted at other venues and not in the Masaajid. This will prevent disrespecting the sanctity of the Masjid.
