Alright, I do apologize for the delay.
Button Text (XFBML)
We do have a quick primer on how to use the FBInvite module (to which you've responded already, which caused me to re-read it). There was (fixed now) an error in that thread.
The below parameter will fix most of the questions you ask for (The string XFBML showing up all over):
Invite Type - This is what the blue button at the bottom of the invite module says for the user to click on. "Send XXXX Invitation" where XXXX is what you put in this field.
For anyone else who wants to read the full thread of configuration parameters:

Skip button
As for the "Skip" button, there is no way to get rid of this. The invite module is pulled from Facebook's page, and they include that. However, if you are interested, you can change the text to any of the following: "Skip this step", "Cancel", or "Skip" by adding the following line to this file:
modules/mod_jfbcinvite/tmpl/default.php (line 30):
<fb:multi-friend-selector
showborder="false"
actiontext="<?php print $inviteActionText; ?>"
bypass="cancel">
Replacing "cancel" with either "step", "skip", or "cancel".
However, using firebug and looking at the returned code, the skip buttons are contained in the following id tags: "skip_top", "skip". If you're interested in adding the following to your template css file, it may hide these 2 buttons (Not tested):
#skip_top, #skip {
display:none;
}
Sending Invitations
Finally, as for sending invites... There is no confirmation for sending invitations, you have to 'trust' Facebook on this (it's not done by the module itself). You can use the module parameter "Post Invite Action Url" to redirect users to after the hit "Send". This would ideally be a Joomla article you've created to thank your visitors (provide confirmation) for sending the invitation.
Invitations that are sent by selecting photos are sent to their Facebook home page, similar to other application requests (Lil Green Patch, Racecars, etc). They are not emailed to the user. If you use the "Invite friends not on Facebook" button in the top right and are inviting your friends this way, emails will be sent to them. We just tested this on the facebook.sourcecoast.com site and it appears to be working. If this isn't working on your site, could you try on our demo site and report your findings?
Thanks again for your patience, and sorry for some of the confusion with the module.
