Here are a few cool tips: Add best friends to your Close Friends list. That way, you'll see more of them in your news feed.
If you don't need to stay in frequent touch with a friend - or just want to see less of them in your news feed - add them to your Acquaintances list. Now their updates will rarely show up in your news feed.
Restricted lists are for people you've added as Facebook friends, but with whom you don't want to share everything you post.
Maybe you accepted a friend request from your boss, for example. Put him on your Restricted list and he'll only be able to see your public posts, or posts you tag him in.
Want even more control? Create a list of just people you want to see. Then click on that list. You'll see a news feed with only those people.
