Theophilus and Tack both make good points, I would like to add to what they have said. Those who will be in heaven have made a choice to be there and in that choice we have received grace and understand what God has done for us, we will find no need to exercise our freewill in a sinful manner, so yes there will be freewill in heaven. Even those who will live in the darkness of hell will have freewill, because they had no change in heart they never experienced grace and will find no reason not to keep on with there sinful attitude. Each will be alone and can do no harm to others, so for those who read this and go to hell you will find no pleasure there.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
