How Do I edit the Power Store 3 Site before uploading to the Remote Server?

Hi, I have installed the MYSQL PHP for the testing server. The next step is, how do I upload the files from power store 3 zip folder to the MYSQL testing server to edit it? Also, could I edit the components in the power store 3 in Dreamweaver or MYSQL testing server utilizing other extensions such as Creative Dreamweaver Show Pro, Creative Dreamweaver Menu Pack or Flexi Panels? Additionally, every time I clicked on the live view or the Preview in other browsers available in Dreamweaver CS5 to view the files, it always directed me to a separate browser with the installation wizard page. How do I stop this? If I choose not to stop this process and just go with the installation but have not uploaded to the hosting server, will this process finalized the installation? Will I be able to go back and modify the site after uploading? If I were to complete the installation without first uploading it to my remote server, will I be able to upload the files and install it again? Thank you for your reply and assistance.
