Temporary Web design

I've decided it's best to make minor design changes to my existing site so that I can upload the pages to the new site sooner. Most of the changes can be done through style sheets; however, many changes require tedious manual revisions to each page. This is just a temporary solution. A design overhaul will come later. Aside from the design, I need to change the code to make updates and maintenance easier. I may need to incorporate a database--something I'll never tried.
