Repeating the sajdah tilaawah aayah in a musjid or classroom

Q:

1) If I am reading a sajdah tilaawah aayah repeatedly on the same spot, then only one sajdah is compulsory. However, if I am in a musjid and I am reading the same aayah while moving around, then how many sajdahs do I have to make? Does the distance I cover while moving around make a difference?

2) If I am reading the same sajdah aayah in madrasah in the same classroom but at different spots, then how many sajdahs do I have to make?

Memorizing a Surah and imagining one is reciting it in front of people

Q: Someone is trying to memorize Surah Yaseen and recite it like Omar Hisham al Arabi. But when she try's to recite it, she imagines that shes doing it in front of people and imagines that she will recite to others later. She feels sad thinking that she can't focus on the fact that it should be only for Allah.

Should she stop memorizing? Should she take an oath that she will never recite "like that" in front of people? She also thought that she would recite beautifuly like that in front of her future husband. Is there any duaa for this?

Receiving the rewards of reciting the daily surahs when recited in nafl salaah

Q: Will we get the respective rewards and benefits of reciting Surah Waaqiah, Surah Mulk and Surah Sajdah if we recite these surahs in nafl salaah (Tahajjud) at night or do we have to recite these surahs before sleeping without being in the state of salaah? Similarly, by reciting Surah Yaseen in Ishraaq salaah, do we get the rewards and benefits of reciting it in the morning as mentioned in the ahaadith.
