Okay, #1 is actually a semantic problem, and on closer reading your description is accurate but could use a slight tweak for clarity. You are pulling the email address for the SITE as a whole, not for the admin-level user. Maybe something like this would help:
"Your SITE admin email address (http://example.com/wordpress/wp-admin/options-general.php) will be used."
Just something to indicate that you're not pulling a user-level email address.
#2 is still a problem.
