Reciting a longer Surah in the second rakaat

Q: Assuming in the first rakaat of witr, one recites Surah Lahab and Surah Ikhlaas in the second rakaat. Is it necessary to make sajda sahu as only Surah Falak or Surah Naas can be recited in the third rakaat but these Surahs are longer than Surah Ikhlaas. Likewise, in any other namaaz, if one recited a Surah in the second rakaat that is slightly or much longer than the surah recited in the first rakaat, what is the ruling?

Making another wudhu without having done any act of ibaadat

Q: In Talim ul Haq Masaail pertaining to wudhu it says in number 13 - It is Mustahab (preferable) to make Wudhu for each Salaat even though one may be in the state of Wudhu. It is Mustahab only if at least two Rak'aats Salaat have been performed with the previous Wudhu. Thus if one did not perform any Salaat, it will not be permissible to perform fresh Wudhu before that Wudhu
has been either broken or at least two Rak'aats Salaat have been performed.

1-Is the above correct?

2-Will a person be sinful for doing fresh wudhu, if the wudhu is not broken or two Rakaats hasn't been performed because it says it will not be permissible to perform fresh Wudhu?

Doubts regarding making ghusal under a shower

Q: I made ghusl. I gargled a couple of times and put water on the nose couple of times then soaped the whole body once including the arm pits and under the private parts also inside the anus will the fard ghusl be done I can't remember if the bend near the anus got wet and the hairs on the anus got wet I was making ghusl under the shower so will the fard ghusl be done?

Scars

Q: A person has a rash like eczema on his scalp. Sometimes it bleeds a little. At night unconsciously he scratches it and it bleeds sometimes. Now it is very difficult to know where it bled etc, and at fajr time he simply makes wudhu as normal without washing his head. There may be some dry blood on his head. Is performing salaah in this manner permissible or does he have to wash his head completely every morning to make sure there is no blood? Sometimes for Fajr he has to be the imam of a small musallah when the Imam is not there?

Hadith Question

Q: I had a question regarding one narration. Did the prophet (Sallallahu Alayhi Wasallam) say that we should wear clothes like the people of the time? Like dress like them? If yes then what does this hadith mean?
