Answer 1

 $showcaseproducts1 = Mage::getResourceModel('catalog/product_collection')
        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
        ->addFieldToFilter('showcase',array('eq' => 1))
        ->addFieldToFilter('status',array('eq' => 1))
        ->setPageSize(6);

    $showcaseproducts1->getSelect()
        ->joinLeft(
            array('mp' => $showcaseproducts1->getResource()->getTable('marketplace_product')),
            "e.entity_id=mp.mageproductid"
        )
        ->where('mp.userid=163');
