Help with archiving articles

Please look at my site http://londonsstories.co.uk

As you will see, there are a series of images which are of interviews with people. Some of the interviews are different. I.e. There are some anonymous interviews, some features, normal interview etc.

I want to create a different page for each of these different types of interviews so that if readers only want to read one type, they can select to go to that page and then from there they can read all of the one type. How can I do this?

I also want the articles to go here when there are over a certain number on the home page. How can I limit how many are on the home page and how can I control where they go to be archived after the home page is full? Surely this must be quite simple. Sorry if I am irritating.
