Ayatul Kursi is the greatest verse in the Quran. It is a protection from the jinn. It is never recited in a house but the Shaytan leaves. It contains the greatest name of Allah.

There is no evidence that the person who reads the Quran translation will earn the reward of reading it in Arabic. But, if a person reads a Quran translation in order to understand the meaning and benefit from what the verses are saying, then he will be rewarded for doing this, and his reward is with Allah.

You should act upon the sound hadiths that describe the virtues of Surat al-Ikhlas. So recite it as many times as you wish, without sticking to a certain number or time or way that is not prescribed by Shari`ah.
