Llp incorporation

Hi, 

I am trying to incorporate a LLP for the first time. I have few queries. Please guide.

1. There are three individual members in this LLP. So two should be declared as designated partners. Am I correct?

2. Should DSC and DIN needed for all three members or only for designated partners?

3. Earlier designated partners needed to give their consent in form -7. Is it still required under new procedure ? If yes, where should i submit the consent?

4. Is it necessary to add LLP at the end of the name of the firm?

Thanks
