I have been white labeling word press with variuos levels

I have been white labeling word press with variuos levels of success.

The word word press can be pretty much removed from text by using the branding plug in

We still have the urls to deal with.

Word press allows you to change the name of wp-content and includes. But not wp-admin

Using .htaccess and making a copy of the wp-admin dir i have been able to get most functions to work by pointing easy blogging buttons to my copy of the admin directory...
but some functions still must use the wp-admin dir as originally named or they do not work.

So here are my questions

1) Has anyone found a successful .htaccess way to hide the wp-admin part of the url?

2) is there a plug in that would help white label word press
