Most of those answers can be found among LL rules or within this board. You just have to look.
When you are new its overwhelming and I understand. Honestly, I say read thru this board & the submit rules again. Take a look at what sites are listed at Link-O-Rama and how they are structured. Do not copy but use them as a guideline. Piece one together and then graciously post it for review, before you submit, and get feedback.
I have given this advice to one person that I know actually followed it and he is doing just fine
