My suggestion would be to have your references be internal, as in, people you've worked with within the company. If you know that a certain person you've worked with would give you a strong recommendation, then that's the kind of reference I'd put down. That also goes for people you've worked with in a previous job/company, but you want to have an emphasis on the current colleagues you're working with now. Not sure how big/small your company is, but if it's one that's relatively small (<100), odds are likely the staffers will know the folks in your department.
And yes, put down any and all mention of contributions, accomplishments, skills, etc. After all, you want to make yourself sound more invaluable to the company than anyone else who's interested in that job.
