all of our throttle body pnp services include a brass connector used to "byepass" the stock coolant lines. The connector has two male connectors much like your stock throttle body. This simply connects the two hoses so that the coolant still flows, just not through your throttle body. I'll try to dig up some pics, but you can refer to scoobymods.com for a very similiar modification.
As for the IC elbows, the pictures shown above of are the stock elbows used with the stock intercooler. The two metal pipes your refering to are correct. We usually recogmend this service for people with samco hoses to help maximize airflow. We also have done many aftermarket y hoses (turboxs, etc).
