Why are the changes I made in my admin not showing on my product pages?

[Jay Gee]

Greetings!

I am trying to get administrative changes made to my product pages to show up when the pages are viewed and, am not having much success. For example, I have turned off the Write a Review, Tell A Friend, Product Added Date and Display Product Quantity functions, but those items and buttons are still there when I call the pages up.

After changing layouts for product categories, do existing product pages need to be re-entered and regenerated so that new outputs incorporate the changes called for?

Thanks for your help.

Jay
