Reserve 24 vanilla wafers whole and set aside.
Place the remaining vanilla wafers in a large zipper bag or food processor and crush into fine crumbs.
Mix the crushed wafers with 6 tablespoons melted butter until evenly combined, then press the mixture firmly into the bottom of a 13x9-inch pan to form the crust; refrigerate while preparing the filling.
In a bowl, beat the 8 oz softened cream cheese with 2 tablespoons sugar using an electric mixer until smooth and blended.
Fold 1 cup of the thawed COOL WHIP into the cream cheese mixture until smooth, then spread this layer evenly over the chilled crust.
Stand the 24 reserved whole wafers around the edges of the pan, pressing gently into the cream cheese layer.
In a medium bowl, whisk together the two 3.4 oz pudding mixes and 2 1/2 cups cold milk for 2 minutes until thickened.
Stir 1 cup of the remaining COOL WHIP and 3/4 cup of the toasted coconut into the pudding until combined, then spread this coconut pudding layer evenly over the cream cheese layer.
Top with the remaining COOL WHIP and sprinkle the remaining toasted coconut evenly over the top.
Refrigerate the assembled bars for at least 5 hours or until set before slicing and serving.
