Very confused on setting up drums in reaper with efnote kit

So I downloaded reaper, downloaded stevenslate drums and have ASIO4ALL and ASIO 2.0 efnote installed.

I'm assuming I should use the efnote program but when it's selected I'm not sure what to select as first or last for the inputs. I asume 1st is 1/2L and last is 7/8 R? On my efnote module I set it as profile D but not sure what is correct.

For the output device I only see efnote as an option but obviously I want that to be my headphones. The other audio systems give me an option for my headphones so why isn't this? I'm not using an audio interface as I've been told the efnote module sort of works as one though once I get it working I assume I'll buy one to fix the latency I've been warned of.

Module wise, what do lines 1-8 even mean? I'm super new to anything related to midi and handling audio so I'm very confused on all this.

When I add the virtual instrument track it tells me if I "want to add the following tracks for this effect. If not, only the stero 1/2 outputs will be audible without further routing. Stero 1/2 -> new track 2 'out put #1' " Is the module doing this "further routing" its talking about so I don't need to click yes, or should I be hitting yes and creating a ton of separate tracks.

So basically I need help
