It looks like the screenshot above is of the SCLogin module. If changing the SCLogin > Social Button Settings for Orientation and Alignment and updating your theme CSS as needed does not give you the positioning you require, you'll have to do a template override of /modules/mod_sclogin/tmpl/login.php to place them elsewhere in the module. We also currently don't have an easy setting to remove the Social Network buttons, but do have this as an issue in our tracker to address in the next release. While not ideal, this can also be currently worked around with the template override as well.
If you're not referring to customizing the SCLogin module, then please provide more details on what pages/URL's you're looking for changes for.
Thanks
