Do I need a Y-adapter for both inputs if I'm running LFE and my sub only has Left & Right inputs?

No. If your receiver/preamp has a single subwoofer output, you will need to only connect it to the single Sub-In input on your subwoofer. Adding a Y-split cable will just raise the volume which can be achieved by using the volume knob.
