These options control the default look and feel of Hyperseek. The options are straight forward. First you will set your colors and styles. If you are planning on using CSS to design the look and feel of your site, delete the color and text options form the "Color and Styles" section, making sure they are all blank. If you do not, these options will override your style sheets.
Go through the Search Engine Specific Style settings and adjust these to best fit your site. If you are using CSS leave the options "What color should category links be?" and "Listing Link Color" blank.
The last section on this page is the "Content Match Display Settings". You will need to read the documentation for more information about Content Match. In a nutshell it is "Google Adwords" like content for your affiliates. You will need to set this up before offering this section to your affiliates.
