Benefit of reciting Aayatul Kursi

Q: Can you please provide guidance on the benefits of reciting ayat-ul-kursi? I have been told:

1. Recite ayat-ul-kursi before going to bed.

2. Recite ayat-ul-kursi after making wudhu.

3. Recite ayat-ul-kursi after reciting your fardh salaat.

Please provide insight into the benefits of reciting ayat-ul-kursi for the above 3 occasions and also if there are any other occasions when you should recite ayat-ul-kursi.
