Qur'an

Imaam going into ruku after reciting a sajdah aayat

Q: A few days ago, our imam recited Surah Alaq in the second rakah of Isha salaah. When he recited the aayah of sajdah, he did not perform the sajda-e-tilawat but went into ruku' and completed the salaah as normal. 

My question is: was he right in omitting to do sajda-e-tilawat which my understanding is to be wajib. After the salaah he explained that what he did was permissible.

Touching a booklet that has Quraanic verses and the translation

Q: In my Quran classes we use a para/juz wise booklet. One side of each page has Arabic and it's word to word Urdu translation while the other side is entirely blank lines for us to write the tafseer and notes. There are a few pages of Urdu notes in the starting and ending too. Can this be touched without wudu, because writing tafsir and making notes daily would be a lot difficult otherwise.
