not exactly sure what you want to do, but based on what you have written, I believe you should be able to hook into:

sph_share_this_chicklets

its a filter where you are pass 5 arguments:  $out, $options, $style, $url, $title, $summary

$out is the markup about to be written out..  you have access to $url, $title and $summary... you probably have to do a string replace in $out for those variables with what you want...

do you know how to do a standard wp hook?  something like:

add_filter('sph_share_this_chicklets', 'my_sharethis', 10 ,5);
function my_sharethis($out, $options, $style, $url, $title, $summary) {
    # now adjust $out however you want
    # be sure to return it
    return $out;
}

settings???  did you try the filter I suggested??

invasive?? nothing invasive about using a hook... means you only make change once and dont lose it on updates...

I do not understand what you want...  but I dont see how the seo options affect what is passed to facebook...  we share a url, a title and a summary (ie excerpt)...   the opengraph seo usage can impact the image shared...

but if you want to change the url, the title or the summary, you need to adjust via the hook I gave you...
