I posted a way to save your Safari tabs to Evernote, which I’ve found is generally a great way to save bookmarks. It syncs automatically to your other computers and your iPhone, and it’s fast and easy. If you really want to highlight a few tabs to make sure you get back to them, you might consider this script, though. Once you’ve saved your entire Safari browsing session for later, close everything except for those special urls, run the code below as a script, and your open tabs will be saved as entries in your InstaPaper account.
