Configure Magento Template

We already have the magento template <[login to view URL]> - installed on our server however, it does need to configure so that all the fields, fonts etc.. display correctly. Right now, the coloumns are off etc... I would like to to be configured where it goes well with our current site. (colors etc..) and would like to keep the same style of as in the template shown above. ( as far as what is displaying on the home page) Also, will like the coder to insert a few pictures in the slide that is build on the home page.
