You don't have to say anything at all. First of all, you have to wait for the avel to speak, so you just wait to see what they say and then take their cue. If they don't say anything, you don't say anything.
Right. They are focusing on their loss. It is not your place to minimize/alleviate/intensify/etc. it.
Your job is to go. Just showing up at a shiva shows that you care, no words necessary.
If you want to go above and beyond, bring some food.
