shaving

Q: I live in Pakistan. In the community I live, its pretty modern. I'm 17 and have beard which do not fully cover the face. The problem is that its is out of shape. On the side burn and under face its is too much, while on the cheek there is nothing. People usually mock me. Am I allowed to cut the extra hairs, Not shaving until the beard totally covers my face and then start growing it on level base. My father is posted to capital of Country which most advance area as well as modern. All my old friends live there. When they will see me with disordered beard, they will surely mock me.

Q:

1. Is it permissible for a person who is clean shaven (due to medical reasons - acne) to be Imaam of salaah?

2. If yes, would it still be permissible when there are Ulama and Huffaaz who would meet all requirements of an Imaam?

Q: I want to ask a question about cutting or shaving hairs from body. I have notice that in modern age every professional works with new techniques or formula. Last time i have seen a barber cutting hairs with fire and other one cutting with special jelly. Some locals told that this method is haram in Islam and it is proved by ayaat or hadith only metallic cutters allowed for men for shaving purpose from different parts of body. Kindly guide me on this topic.

Q: What is better, to offer Salaah behind a temporary Imam who don't have a beard and his pants are below his ankles and I am not sure about his level of Islamic knowledge or alone without jamaat?

Q: After shaving at home without bathing, can a person go for namaaz?
