Right now, we don't have a way to re-arrange the buttons without modifying the code of JFBCOnnect itself. We do the ordering in such a way that it generally lays out the best. Things like Facebook can use text at the end (in standard mode) and Google uses a large popup, so we don't normally recommend altering the order.. though, if you absolutely need to, we can help point you to the file to edit.
As for the Share button, there is no counter for that widget. The only Facebook sharing option that gets a count in the Like button itself. Sharing is just a different way to post content, but is not an indicator that someone actually "likes" the content, and therefore doesn't add to an overall counter indication.
I hope that helps explain, but if you have any other questions, just let us know.
Thanks,
Alex
