Following I give some example which I have done before. Mine contains one edit form and one ajax grid, but with this logic, you can add any number of tabs and grids in this form. File structuire:

enter image description here

/**
 * Experts management Grid container, row click opents expert edit page
 */
class Ssd_Experts_Block_Adminhtml_Experts extends Mage_Adminhtml_Block_Widget_Grid_Container
{
    public function _construct()
    {
        $this->_controller = 'adminhtml_experts';
        $this->_blockGroup = 'experts';
        $this->_headerText = Mage::helper('experts')->__('Manage experts');
        $this->_addButtonLabel = Mage::helper('brands')->__('Add Expert');
        parent::_construct();
    }
}

}

I hope you can understand file structure using class names. some codes are cutted out. My experts edit form contains edit form container, tabs, end each tab content is can be form controls, grid or any content what you want. Additional comments are in the code. Hope this example helps you.
