surah waaqi'ah

Q: A radio station broadcasts Surah Waaqiya immediately after the Magrib Azaan. Is it permissible to delay performing the Maghrib salaah by about seven minutes and listen to the recitation of the Surah first?

Q: I came to know about Surah Waaqi'ah that if any one reads it 41 times daily for a year, Allah Ta'ala will make him ghani? Is it true? And if yes then can I read it any time in the day in parts or there should be a particular time for it and durood shareef should also be read before starting and after ending?

Q: Which Surahs are recommended to be read and when based on authentic Ahaadith?
