2 Problems

I want to display a different amount of posts for different category pages. For example i want the home page to display 9 and the artists page to display 15 posts – i thought this would be an easy function but i can’t seem to find a way to do it.

Secondly is the pagination, currently pages are displaying 6 pages but i’d like to shorten this to 3 pages.
