Well you've got the hardest part out of the way. Right now work on getting your utilization down and the credit limit increases should come with that. Don't know what you have now but once you get your utilization down,you may be able to apply for more favorable cards if that is your goal.
Remember time and responsible debt management is the most important factor in rebuilding your credit. As you are already doing eyeball your report and make sure that everything that should be included in BK is and showing 0 balance owed.
