You can change an object anytime before the ajax call if you have a reference to it.

var obj = {
    url:            'upload.php',
    dropArea:       '#drop_here',
    remotePath:     'user/user1/'
};
obj.remotePath = 'user/user2/';
$('#uploader_div').ajaxupload(obj);

EDIT in response to more code

I read through the docs you are supposed to pass a standard jquery options object to ajaxupload. Right now you have a mix of jquery options and the data perhaps see the jquery docs for more info on what settings are valid.

A simple fix might be putting your current data in the data options attribute.

$('#uploader_div').ajaxupload({data: obj});
