Answer 1

try setting flex property in second panel

    new Ext.Panel({
        title     : 'Panel 2',
        border    : true,
        bodyStyle : 'border:1px solid red',
        layout   : 'fit',
        html      : 'PANEL 2 AREA',
        flex      : 1

    })

flex is only used when Component is rendered by a Container which has been configured to use a BoxLayout. Each child Component with a flex property will be flexed either vertically (by a VBoxLayout) or horizontally (by an HBoxLayout) according to the item's relative flex value compared to the sum of all Components with flex value specified.

You should use flex property for the second panel.

new Ext.Panel({
    title : 'Panel 2',
    border : true,
    bodyStyle : 'border:1px solid red',
    layout : 'fit',
    html : 'PANEL 2 AREA',
    flex: 1
})
