</layout>

Answer 1

Just Remove Code from Customtabs.Xml

<adminhtml_catalog_product_new> <reference name="product_tabs"> <action method="addTab"> <name>my_custom_tab</name> <block>customtabs/adminhtml_catalog_product_tab</block> </action> </reference> </adminhtml_catalog_product_new>

Override Block Tabs.php Mage_Adminhtml_Block_Catalog_Product_Edit_Tabs added code

$urlparm = $this->getRequest()->getParam('set', null);
    if(isset($urlparm)){
     $this->addTab('customtab', array(
                'label'     => Mage::helper('catalog')->__('My Custom Tab'),
                'content'   => $this->_translateHtml($this->getLayout()
                    ->createBlock('customtabs/adminhtml_catalog_product_tab')->toHtml()),
            ));
        }

Answer 2

Just remove

<adminhtml_catalog_product_new>
    <reference name="product_tabs">
        <action method="addTab">
            <name>my_custom_tab</name>
            <block>customtabs/adminhtml_catalog_product_tab</block>
        </action>
    </reference>
</adminhtml_catalog_product_new>

from customtabs.xml

adminhtml_catalog_product_new layout has been used for 1st step of product that means when we have selecting a product type during product creation

Answer 3

I assume that your custom tab class extends Mage_Adminhtml_Block_Widget_Form and implements Mage_Adminhtml_Block_Widget_Tab_Interface.
If it doesn't it should.

Then you are obligated to implement the method canShowTab.
Here you can put your code to determine if the tab should be shown.
Something like this:

public function canShowTab() {
    //get the current product instance
    $product = Mage::registry('product');
    //if on edit mode show the tab
    if ($product->getId()){
        return true;
    }
    //if on add mode and the attribute set has not been selected yet don't show the tab
    if (!$product->getAttributeSetId()){
        return false;
    }
    $request = Mage::app()->getRequest();
    //if creating a configurable product and you have selected the configurable attributes, show the tab
    if ($request->getParam('type') == 'configurable'){
        if ($request->getParam('attributes')){
            return true;
        }
    }
    return false;
}
