Answer 1

The easiest way is to implement your own TableModel

public class MyModel extends AbstractTableModel {
    List rows;

    public int getRowCount() {
        return rows.size();
    }

    public int getColumnCount() {
         return 4;
    }

    public Object getValueAt(int row, int column) {
        return rows.get(row).getCol(col);  //assuming your row "Object" has a getCol()
    }

    public Class getColumnClass(int col) {
        return Boolean.class;
    }

    public void setValueAt(Object aValue, int rowIndex, int columnIndex) {
        rows.get(rowIndex).getCol(columnIndex).setValue(aValue);
    }

}

Load this into you JTable. If you haven't replaced the default cell renderer for Boolean's, all you cells will be rendered as check boxes thanks to you implementation of getColumnClass(). All user input to these check boxes is collected with our setValueAt().
