remove some tag and cloud function

Which line in which php file do I need to take out to get rid of the tag and category buttons in the post list index and at the top of each post when they have been opened? I don’t want to completely remove the tag and category system as I am building nice tag and category clouds…just not have them associated with the post on the index page or indeed at the top of the post when it is open.

Thanks, Paul. 35 and 3/4.
