Need some clean up on my Wordpress site

Paid a friend who is a Senior Dev at a company here to redo our website which I originally customized based off of a theme and now the theme's functionality is a bit out of whack. Here's what I need done:

- Links to go to proper pages
- Blog posts to not show up on random pages
- Text that's typed in when creating a new page to show (i.e. there's text written for the top of pages and it only shows the gallery now)
- Just a general clean up / get everything tighty so it all functions properly.

Should be fairly quick and easy for someone who knows what they are doing.
