Setting Up Menus

I cant figure out how to do this and I have tried searching on the internet for good tutorials. Is there a place on here that will guide you through the process. I am generally technologically very competent but something is not clicking and I cannot make the menu system work on here.

First of all I am trying to create two menus a blog menu and an about me menu. as of right now I am only able to get one menu up at a time. when I get one up and try to assign content to that menu the content shows up next to the menu and not in the menu itself. I have tried creating pages and posts and assigning them to the menus. I have deleted and recreated menus. I have switched skins. I have tried simple HTML to create separate links as recommended by a course I’m following although I’m still not clear how I’m supposed to add content to them (I was only able to make that work once and it wasnt really want i wanted). I dont get it and it’s not working. I really need help. It cant be this complicated to do. The about me page needs one post and I wont touch it again. The other menu will be added to on a weekly basis.

The page I need help with: [log in to see the link]
