Apache 2.2 setup on Windows Server

Installing Apache 2.2 on a windows machine, I need to have setup & learn how to the server. We are changing the web server to Apache from an existing web publishing setup, so I need the new apache to do a few things. 1.) Display each domain in both the www. & just the [login to view URL] 2.) make sure the PHP works on all sites 3.) make sure the ZenCart site are running appropriatly 4.) keep all the existing paths for the sites php and such so that other PHP pages and links do not all need to be repathed. "or in other words, just have the web path to the site docs the same as it is now, NOT apaches WWW default path to the web content" 5.) make sure the MYSQL is setup so that site like the ZenCarts will continue to run, as well as other MYSQL setups such as pommo will still be using all the same paths to run. I need ALL the paths to be the same as they are now and just swap out the WEB server software to apache to do the same job that the web server is doing now and be shown how it is done so if it crashes at some point I know how to rebulid. I would guess this can be done in an hour or so as Apache is already installed as well as PHP and the MYSQL, so really is only an initial configuration for Apache.
