facebookprivacy
I am wondering how would I modify my privacy settings on Facebook so that my friends/public would only see our mutual friends, and not a list of all my friends and the number I have?
On a side note, is there a way to modify your settings so that when you change your relationship status (i.e., break up with someone) that it will not announce to everyone?
Are you referring to your News Feed (Top News), News Feed (Most Recent), or the Recent Activity on your profile?
I think that News Feed (Top News) only displays what Facebook considers to be most interesting to you, so I wouldn't expect your own likes/comments there. The News Feed setting that you mentioned applies to the Most Recent setting.
News Feed (Most Recent) does not display individual stories for comments and likes on posts; you would only see them under the corresponding post, if it is expanded. Are you saying that you expanded the likes/comments and you can see comments from other people but your comment is not there? Sometimes it takes some time for it to show up although it shouldn't take days (unless it was deleted).
If you are referring to the Recent Activity on your profile, there is an additional setting for that that you didn't mention. On your profile's Wall (not your News Feed), scroll to the bottom and click Edit Options. If you have hidden any kinds of stories from your Recent Activity these will be listed and you can unhide any of them by clicking the X and then Save.
As for the Photos tab, that used to be a known issue although the link to Facebook Help in that answer does not seem to work now. I don't know if that means that it should be fixed.
It appears there's no way to do this, unfortunately.
What I ended up doing was to do the going-forward arrangement, and then work back a couple of months, making corrections manually (#1). Better than nothing. There is also the issue of my comments on others' posts being visible. In my case, I think this is "good enough", though I do wish there was a better solution available (without programmering).
It might be possible to use the Facebook API to achieve this, but I didn't see anything ready-made with some quick searching.

To modify your friend list privacy, click on the list of your friends on your time line (friends block). In the new page, on the top right section click on Edit and then specify who can see your friend list on your timeline. Limiting this to "Only Me" will not let anyone else to see your friends. Other people will be able to only see mutual friends if they have not limited their friend list privacy.
To edit the privacy of your relationship status, click on "About" on your timeline below your profile picture. In the new page, click on Edit button of "Basic Info" block and edit the relationship status privacy by specifying who can see your relationship. Change it to "Only Me".
