I would lay low with Navy for a while, you do not want to mess up with navy by getting flagged for income discrepancies. I don't think I'd add any other income that's not yours including college grants. My wife and I used our own incomes for our individual cards and joint income for our joint card, better to be safe than sorry when it comes to navy. Take a break, pay down your balances and let your accounts age and reapply. Navy will still be in business in six months and you'll be glad you waited.
