Exposing one's satr in a room wherein there is an Islamic calendar

Q: I always put Islamic books away and don't leave them uncovered incase they get disrespected. I would like to know if an Islamic calendar with no Quraanic Ayahs or Hadeeths are on there, and it just says "Islamic calendar" and has dates are hanging in ones bedroom and if one dresses really immodest like nude and seminude etc. is it disrespectful? And what is the ruling if one thought that it might be disrespectful but ignored the thought and continued to leave the calendar hanging?

Burying Islamic literature

Q: With regards to Islamic literature, for example letters and leaflets that contain the name of Allah Ta'ala and the prophet (Sallallahu Alayhi Wasallam), how are they to be disposed of? Is it correct to wipe away/erase those names and then dispose of the letters in the bin, or must they be burned?
