Making taubah for taking an interest loan

Q: If a person, who in ignorance, took out an interest loan, thereafter realized his sin, made sincere taubah and made a promise to Allah never to take such loans again. However he still has the debt/loan to pay off and he doesn't have the full amount to settle it. Now going forward, does he still fall under the curse of Nabi (salallahu alayhi wa sallam), as he still has to pay off the loan and he will still be paying interest? Please advise whats the way to correct the situation.

Taking an interest bearing loan to save oneself from paying tax

Q: A person deals mostly in cash and does not deposit in the bank in order to avoid showing too much income and paying exorbitant amounts of tax to the government. However, he cannot purchase large items such as properties and cars etc as it has to be done with "legal" money.

The only way out for him will be to take a loan from the bank in order for his purchases to be recognized legally. He will offset the interest payable with the interest he receives from his bank account.

Can this be a valid excuse to enter into an interest bearing loan with the bank?

Carrying out a credit transaction without the presence of witnesses

Q: I am in business of steel and rubber trade in which I used to give material on credit without any witnesses. Recently I heard a speech of a scholar that Allah will not hear your prayers if you had given credit without any witness.

Is there any remedy to my situation and also does the material on credit and money givien on credit come under the same ruling?
