Hi catezapp, we are here to help you learn how to make these kinds of updates on your own. We are not available to make extensive edits for you, and if you'd like someone to edit your web pages and menus for you, then we would like to respectfully ask that you please hire a web designer or developer to help you make such changes.
I know we have helped you with lots of CSS snippets over time, and I would be happy to continue to help you learn to get better at making these types of changes to your site so you can make the updates yourself. As a site owner, you are responsible for making your own updates.
Let me try to give you the best advice possible so you can learn to make these edits yourself:
I noticed that there are two my passions pages that should be removed
one post/article that should be removed
Here is a direct link to your menus page:
To remove the duplicate, find it in the list, click the arrow to the right of the one you want to delete, and click the "Remove" link that appears.
also would like to add a portfolio page named Cate's portfolio also on menu
Before you can add a post or page or portfolio project to a menu, you must publish it publicly first. So, if you would like to add a page named "Cate's portfolio," then first you should go to Pages > Add New in your dashboard and create and publish a "Cate's portfolio" page. Once that is done, you can go back to Appearance > Menus, make sure the primary menu is selected (you should see this at the top of the page), then click Pages inside the menu selector, find the page you create, and click the "Add to Menu" button. After the page has been added to the menu, you should see it in the menu structure on the right and you can click and drag to move it into the right place in the structure.
There is also a detailed help page about how to manage menus at http://en.support.wordpress.com/menus/ which has step by step instructions, pictures, and it even has a video in case that works better for you to learn how to setup menus.
