moving menu items in K2 reloaded

I’m redoing my business website with K2 reloaded and WP 2.1.2.

I’m not using the blog features, so I’d like to get rid of the blog link in the nav bar. I’d also like to move the site admin link to the footer.

I’m new to php and wordpress, so if someone could give me a simple but descriptive answer (if possible) I’d really appreciate it.

Thanks.
