What is the best way to load the WP environment in a subdomain of my multisite WordPress install?
Use the defines to make it pick the site you want it to pick. You can define these four to setup the $current_site values properly: DOMAIN_CURRENT_SITE, PATH_CURRENT_SITE, SITE_ID_CURRENT_SITE, BLOG_ID_CURRENT_SITE.

When is wp_loaded initiated only with admin or only when user enters the site or both?
wp_loaded fires for both the front-end and admin section of the site. This action hook is fired once WordPress, all plugins, and the theme are fully loaded and instantiated.
