Adding functions or pages to a theme

Hi everyone.

I have been using a great WordPress theme(NextWP) for a online magazine I am part of. The theme looks great and all but the support is terrible as we never get a reply to the emails.

Anyways one thing the theme didn’t have that I needed was an about page template. So what I have done is coded it manually in Sublime Text 2 and then added the html to a new page using Text mode and then I add the CSS to custom.css file in the theme settings.

The problem is that WordPress adds p-tags and stuff in between the image and H3 and makes extra white space.

You can see the page here. http://www.spetakkel.org/spetakkelet/.
Is there a better way to add this page for a WordPress newb?

Thanks for any tips..
