Can a person who possess a cellphone or a car receive zakaat

Q: I heard from an Aalim that if a person has a fancy touch screen cellphone, then he cannot be given zakaat.

1) If a person has a cellphone worth R3000k and jewellery worth 3000 and 1000 cash, does zakaat now become wajib on him / can he receive zakaat?

2) If a person has a car worth R500 000, has jewellery worth R10 000, cash R10000 but is in debts for R20 000. So his balance is 0 excluding the expensive car. Can he recieve zakaat? Even though he has such an expensive car?

Committing sins

Q:

1) I heard many times from many people that if you satisfy your sinful desires in this world like drinking wine, wearing silk etc, these desires will be taken out from you in Jannah, is that true?

2) I thought even if you commit sinful acts or desires like drinking wine, wearing silk, if you repent you are forgiven so if you repent would Allah still take away these desires from you?

3) What worries me that if I drank wine, wore silk clothes, ate on gold plates etc I wouldn't do these things in jannah (paradise), if I committed those things, if I repent would that be enough?

4) Does Allah forgives sins if you repent without namaaz?or you have to pray namaaz to get your sins forgiven of drinking wine, wearing silk clothes?

Suspending the talaaq

Q: Will the talaaq take place if my husband suspends the talaaq upon any action that he does. For example, he says "If I watch porn, then my wife is divorced". Then, in the future, if he does watch any porn, will the talaaq take place? Similarly, what is the Shar'ee ruling if my husband suspends the talaaq upon any action that I do? For example, he says "If you go to your friends house, you will be divorced". If I then at any time in the future go to my friends house, will the talaaq take place?
