Well now that you already have your Kohls card, do not cancel it. Pay if off as fast as you can, and every few months charge something small to it and pay it off in full to keep it active. Your doing fine with two cards. I would keep those for awhile and in about 6 months to a year, ask chase if you can get a credit limit increase. After about a year I would apply for another prime card(amex, citi, discover, chase, boa).
