Setting up an ebooks website

Q: I want to start a website where people can download books for free. Normally, we download books from other websites and upload on our website. People come and download the books. My questions are:

1. Is it permissible to make books available for free download without the permission of the authors?

2. Downloading books from others and making soft copies of your own seems wrong. Is it a sin?

3. Is the money made from such a business haraam?

Disposing of literature of other religions

Q: The following situation befall me: I went to the toilet and seated on it and while I was doing my need, I saw under my feet a catholic newspaper was spread down. I saw words like "god". I hesitated whether I should remove it while doing my need or whether I should leave it. Then my mind decided that since it is a catholic newspaper and the word "god" is not like the name "Allah" I should leave it. Then after I finished and went to flush the toilet, I had still some hesitation and I took out the newspaper and looked what else was written and found in the inside also sentences about a death news "may she find rest by god". Then I just put the paper outside the toilet. Now was it kufr that I left it inside the toilet and not took it out immediately once I saw the word "god"?

Intrauterine insemination

Q: Iui is intrauterine insemination. In this semen of husband is taken in a vial, it is then injected directly into the uterus of woman. My freind had a female child 10 years after marriage by this procedure, she wants to have it one more time. Is it permissible for her?

Imaan and Salaah

Q: We hear in jamaat bayaans that Nabi Sallallahu Alaihi Wasallam and sahabah made effort on imaan for 9 to 13 years, sometimes we hear 11 to 13 years, before salaah and other commandments came down. What should one say, 9, 11, 13, years effort of imaan was made before the commandments came down from Allah?

Musaafir changing his intention and staying for more than 15 days
