Language Checker module provides a tiny little overview page which lists each installed module's translation percentage for each enabled language, and overalls.
This module provides per-language access control for creating and updating nodes by adding a list of checkboxes for each available language to the user add/edit form (only visible to users with 'administer users' permission). These language permissions are combined with the normal user permissions to give more fine-grained access control.
Translation Links module creates links to translations in convenient places for semi-multi-lingual sites, such as next to teaser titles, as local tasks (aka tabs) and on node/edit pages.

Requires Drupal core's Locale and Content Translation modules.
