you can make it so people have to have mutual friends with you to send you a request, but you cannot just completely disable it

the last thing you ask just isnt possible at all, there's no way to hide the comments you leave, you can only hide the notification that gets sent to your other friends when you leave a comment by using the restricted list, but that isnt quite what you wanted to be able to do

in short, facebook is for sharing your activities with your friends and it is not meant to be completely private like you want it
