The template you selected when setting up VWS is the template you will have to edit. If you edit the created page from the template, those changes you have made on your index.html page will be wiped out the next time the VWS copies the template to the server.
I suggest you make a new copy of the template and work with that so in case you need to reference the original locations or how something was displayed you have an unaltered version to go back to. The templates have a folder on your VWS machine and all end in .htx Typically c:\vws\templates
So in any event you can take whatever template you like, copy it and then make the edits to use what seven or five day forecast, icons & text, icons only, text only, or feeds that you want from weather for you. Any and all options all up to you as you code the page. The hard part is finding the content you want to use but once you have it you can find and replace the original VMS supplied data.
