Different levels of guidance

Q: Is it correct to say that guidance is actually from Allah Ta'ala alone, and that when the Prophets gave us guidance, they themselves did not guide us, but it is Allah Ta'ala who guided us? Also, is it mentioned in the Quran that Allah Ta'ala told the Holy Prophet (sallallahu alayhi wasallam), "It is not you who guides them, it is Allah who guides"?

Respect for the Ambiyaa (alayhimus salaam)

Q: Nabi Aadam (alaihis salaam) was in heaven and becuase he disobeyed Allah he was thrown out of heaven. Now my question is that the father did a mistake and Allah is punishing the children who had nothing to do with the father's mistake. According to me Allah should have kept each and everyone in heaven first and tell them not to repeat the mistake which Aadam (alaihis salaam) did. If someone does the mistake then he should be thrown out.

Girls madrasah encouraging girls to wear tight fighting clothes for exercises

Q: My daughter is attending an Islamic Muslims girls Madrasah. After complaints from some parents that the girls are picking up weight and not very fit, they started exercise for the girls. We generally encourage our daughters not to wear tight fitting clothing, and clothing that kufaar wear, but they are forced to wear these types of clothing for their exercises. After asr and before maghrib on Fridays, we generally encourage our family members to engage in dua and ibaadat, but they use this time also for exercise. Kindly advise if this is correct? Also advise what should we as concerned parents do.
