WordPress and JQuery Problems

Well I tried coding BlenderPimp’s web layout by myself from scratch, and it became a major project, plus the comment.php was the biggest issue with me, cause I couldn’t figure it out, so I decided to use the WordPress Theme Generator to generate the theme’s layout, which you can see what I got so far at http://wordpresstest.freeweblayouts.tk/ which is where I test WordPress Themes, and edit plugins, etc: and I already did some minor modifying to it as you can see.

1) So anyway as you can see (if you visited the link) I’m having two problems 1 with the JQuery navigation bar (which is supposed to look, and act like this) So my question is how can I get it to work???

2) Also you may have noticed that the topic is not positioned below the navbar, and centered in the layout like it’s suppose to, and I know the positioning, and that is done in “<u>reset-fonts-grids-tabs.css” where grids is however that’s where I’m stuck, cause idk what I’m looking for after that. So could someone help me out on what to find, and modify (being specific) or code it for me, and help me understand on what’s what, and what it does, etc:

You can download this zip file (72MB) which I coded what I wanted the pages to look like (my CSS is so screwed up though, and needs a fix), however well you can see my php problem lol. So if you could help me with that too thanks. (Also the background isn’t suppose to move like it does navigating from the home page to the tutorials page, and you’ll see that when you download the .zip file)
