Answer 1

Get the record from the recordIndex :

var record = column.up('grid').getStore().getAt(recordIndex) 

Then get the value of the desired column :

var duration = record.get('duration') 

Together :

'checkchange': function (column, recordIndex, checked) { 
    console.log(checked);
    if(checked === true) {
        var record = column.up('grid').getStore().getAt(recordIndex), 
        duration = record.get('duration') 
    }
}
