Finish setting up my new WordPress site using old site data

Kind of design: Theme/template
Num. of web pages: very few
Description of every page: Need to transfer most of the information from my old website to the new WP-based site. Nothing complex, I just don't know how to use WP yet and need something clean to start updating. New site exists in a WP set up as a skeleton. Need to transfer text, config pages properly, and add my custom-design logo (I have it). New site will be small and to the point. I think all of the info is already there (on the old site). The new site will not have any publicly visible blogs.
Ideas for the visual style: Professional look
Extra notes: I will provide the URLs if requested.
