You really need to get your TU and EX scores up first. Lower/pay off other debt (espeically credit cards). The lower your debt to income ratio is, the better. Also how easily the approval will come will be determined by how much of downpayment you make on the home as its easier to approve when the loan is much less then the value of the home (20% down is easier then 10% etc). Also if the local housing market is still going down in price, the approval will be harder, though if that is the case, you should wait for the bottom before buying.
