How to stop loading stylesheets in WordPress admin area

This has been a real pain in the a** as I have been struggling to find out why my stylesheets are loading in WP Admin panel and making it look messy.
I am using the Bones skeleton theme and there’s a style sheet called base.css which adds 20px left to all ul-li elements, now the code I am using in the theme to include base.css is this:

wp_register_style( 'base', BASE_URL .'/stylesheets/base.css' );
     wp_enqueue_style( 'base' );

no other thing is interfering there. Also I am hooking it to the wp_print_scripts like this:

add_action('wp_print_scripts', 'base_styles');

all my javascripts are also hooked to the same hook.
Two issues:
1. Why Javascripts are loaded in head whereas styles are loaded in bottom no matter what the sequence of hooking to print_script is?
2. Why are my stylesheets base.css loaded in admin panel?

I know a solution that I directly add the stylesheet in the head, but having said that, it isn’t the “Recommended” thing to do as per many wp forums.

Please help!
