Questions For Services Listings Page

The attached picture is showing the HydraFacial page and the services for that category.

1) Can you tell me how to add a description at the top of the main category page or is this not possible?

2) How can I remove the category links from the services

3) Is there an option to show or hide the service description on the listings page - the page that shows all the services? When there is a lot of content it doesn't look good. It would be nice to have 2 description fields, one for the listings page where you list the services, and the other where you can put the rest of description and this would displayed on the service details page.

Thanks!

Can I get some help regarding my questions. Thanks!!
