I tested some compatibilities of plugins between RC 0.7 and 0.8 a while ago:

Most of them (at least the ones in development) work fine. For some you will have to get a special version for 0.8.

For the plugins you listed I can only confirm for "password". This plugin is bundled with Roundcube so it works. For the others you will have to try if they're all working. Also check their developers websites if there were changes for larry theme (0.8).
