What might be the best way to connect the MicroVerb. The Audient iD44 has dedicated stereo headphone outputs so I guess I would connect the MicroVerb in-line with these?

Ian, my response here may seem a bit technical but if you take the time to read it carefully, there's some ideas here that I think could really help you grow in your understanding of how your system works.
I respectfully disagree with Fairviews idea of using a small mixer. I think its best to keep the Audient as what we'd call your 'center section'. This means that you want the master volume on the audience responsible for controlling the final signal to your monitors.
The cable connecting your Audient to your monitors should be in line output 1L and line output 2R. DO NOT use your headphone output to send audio to your monitors. It may work but it is not good practice to do so.
If line output 1L and 2R are connected to your monitors, you should then use Audent line output 3L and 4R to connect to your Alesis. Your signal chain should be as follows:
Audient output 3-4 -> Input L/R on the micro verb
Output L/R on the micro verb -> input of channels 3-4 on the Audient.
So the idea is that you are sending the audio out of Reaper into the MicroVerb then back into reaper. Its going in a circle. Its leaving then coming back. That way you control the amount of reverb from inside Reaper. We call this an effects loop.
In Reaper you will have to tell the audio how you want it to go in and out of the system. So you have to tell reaper to send whatever you want reverb on out of outputs 3-4 on the Audient. You do this by creating a separate signal path in Reaper for your very audio to travel out. This path needs to be different from the one going to your reference monitors. This allows you to just apply reverb to the microphone for example.
The way you do this is by creating a 'send' in reaper. You then point/direct the outputs of that send to outputs 3-4 on the Audient. As you turn the send up, it will change the volume going to the Alesis. BUT you won't hear the audio that Reaper is sending out until you create a way for it to come back in. You do this by creating an audio channel and feeding the reverb (created by the Alesis) back into Reaper. How? What you do is create a new audio channel and assign the INPUT of the newly created audio channel to inputs 3-4. Thus you're enabling the Audient to receive the audio coming back from the Alesis and you will hear the reverb.
I realize Fairview was trying to make this simple. I feel its not only better to use the Audient as a your main monitor controller because the Audient sounds better, but also because learning how to move audio out of Reaper then bring it back in is a very important thing to know how to do.
This is a clean and proper way to use a reverb. I would HIGHLY recommend taking the time to learn and understand this process instead of sidestepping it by adding another device.
