There's no way with JFBConnect to send notifications to the user's wall for these events right now. We're planning to add ways to send notifications or wall posts on configurable/programmable events in the future, but don't have anything available for that right now.
It's a tough problem because we have to make sure the recipient has a Facebook account linked on your site, has approved posting things to that account, and then actually pushing the message, which can be from any component. We definitely want to get there, but aren't yet.
