Sounds like you have non exempt equity in the house and cars. If that is the case and you go to a 7 the Trustee will sell the assets, give you the allowed exemption from the proceeds and keep the rest for the benefit of the estate. You really need to discuss this with your attorney.
As to your later post: Reaffirming means that you sign an agreement with the lender that reobligates you to the loan. You make your car payments and keep the car. If you fall behind, the car is repossessed and the lender sues you for the balance.
