The convention for naming plugins on GitHub is phplist-plugin-xxx so you might want to conform with that. The names of the actual php classes are fine.
On the Manage Plugins page there is a “Find plugins” button that goes to plugins:start [phpList Resources] , a docuwiki site, which is where most plugins are documented. You would need to login to that site though, and I don’t remember who controls that. There is a register link on the login page so you could try following that.
I have a couple of comments on the two plugins and will raise those as issues on GitHub.
