Getting just the topic titles in the category pages

hi guys,

so say I’m on a page like this: http://nintendogame.net/nes/super-mario-bros

I want to set it up so that when you click “Categories” it takes you to a list of games (the post title only)alphabetically and not just the full posts. then when you click the title it takes you to the full post.

I would also like to do the same thing for the search function and the Tags.

Thanks!
