If I run the Active Imaging 3n1 on my Live 12 do I still need a seperate 2d transducer?

Define "need"? :)
You can if you want to, the HDS will have full functionality with the 3 in 1 though so this is up to you.
Both. :)
Use the 3 in 1 for idling and drifting (plugged in the black port on the HDS - channel 2), and the puck for on-plane readings. You will probably need adapter 000-13313-001.
The 3-1 will do everything but you might want a 2D transducer in your hull so it can read easily on plane. The 3-1 cannot be put into the hull.
