Phase I trial to study the effectiveness of combining erlotinib and trastuzumab with paclitaxel in treating patients who have advanced solid tumors. Biological therapies such as erlotinib may interfere with the growth of the tumor cells and slow the growth of the tumor. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining erlotinib and trastuzumab with paclitaxel may kill more tumor cells
