Answer 1

I think it's not string $model than you want to put into CActiveDataProvider class ...
So, it's not
CActiveDataProvider('$model', ...
But
CActiveDataProvider('model', ...
Or
CActiveDataProvider($model, ...

Answer 2

error says that you dont have "$model.php" file - so you have to put there valid and existing name for model file.
for example:
new CActiveDataProvider('model', ...
