Hi crystal and welcome to the forum
If you were to enter into an IVA, your limited company would continue trading normally as I assume it is providing you with your incomes. If you have personally guaranteed any limited company debts, these companies will have to be notified as contingent creditors.
You may be required to sell your car if it is of high value - I usually judge £8,000 to be a reasonable sum, however this depends upon your own circumstances. You may still own your own home, but any equity will usually have to be taken into account either at the beginning or end of the IVA. Do you have equity at the moment?
