I have everything I need but I do not want to clone the 500 go to the 1 tb SSD. I want a clean install on the new 1 TB drive. So I can just remove the 500 go ssd then install the new 1 TB drive and download and activate it? I read something about having to make a bootable USB for that.
Just boot into recovery mode, wipe the SSD with Disk Utility and reinstall OS X to the new drive. Once done you can restore via Migration Assistant. It's really quite simple.

You can put the SSD in and boot into internet recovery or leave it attached to the USB and use the recovery partition from the old drive to do the install. It doesn't really matter. If you want to boot off the recovery partition. Hold down the option key by itself when booting and select "Recovery HD". Rather than one of the options in the article. Everything else is the same.
