I got into this thread a little late, but I see lots of good suggestions. I don't know the age group your players are in, or how long they have been playing, but a lot of groups (my first group included) start out with a lot of hack-n-slash stuff and then slowly move more towards role-playing and the story.
You sound as if you've found a RPing ally in your friend, so I wouldn't totally give up on doing that in a game just yet. Others may eventually catch on and join in when they find the video game style getting a bit boring (how many kobolds can you slash before it gets old anyway?)
Some threads have mentioned punishment for your players for some of the things they do, and I tend to agree, but maybe a different type of punishment is in order rather than having the law come down on them. I think it may have been 2E D&D that had a bit of a caveat in giving out XPs to players in that when an encounter is far too easy, the XP awards should be reduced. So, if your players jokingly say they are going to kill of some innocent townsperson or NPC, and they do, when they ask for XPs, simply tell them "none" and then explain why. Not everything they do is going to gain them XP, and they should learn that early on. It might not change their ways immediately, but if they are looking at gaining levels and becoming more powerful, at least it will give them something to think about.
Good luck with your gaming!
