This is my first time, so please be gentle!

I have a new site on my development box at home, which is currently identical to the live hosted site. When I have made changes via the admin menus on the development box, I'm not sure which files I should upload to the live site to carry these changes across.

I don't want to make the changes directly to the live site via the admin log-in, as I don't want customers to see work-in-progress.

I'd prefer not to upload the whole site each time, as the configure.php files are different on the live and development sites, to reflect the different paths on the two computers.
