Filing one's teeth in the state of janaabat

Q: Can a person in janaabat (sexual impurity) do teeth capping and teeth filing? Will the person become pure (free from sexual impurity)? If ghusal is done after teeth filing and teeth capping, does teeth filing and teeth capping in janabah (sexual impureity) have any affect on purity after ghusal, will the person be pure to read namaz after ghusal. Please help me because thinking all this I am going mad.

Reciting Qur'an, reading Islamic books and wearing a taweez in the state of janaabat

Q: I like to ask things I can do in the state of janabah (major impurity).

1) Can I recite or read Quranic surahs from memory when I am in the state of major impurity janabah?

2) Can I read and touch Islamic books, which has Surahs like fazail amal and other Islamic books when I am in state of major impurity janabah?

3) Can I wear taweez which has Quranic surahs when I am in major impurity janabah?

4) Some people say it's ok to wear taweez, others say it's haraam. What shall I do?

Wrong thoughts

Q: I had this dream/thought of these two people kissing and I was awake but had my eyes clothes after I had woken up almost, and my heartbeat didn't go fast or anything but sometimes when I cross my legs my private area throbs so am I napaak? Would this be considered as a wet dream? Also I am on my period if I am how can I do ghusul? If I sit on stuff and use things will it become napaak?
