Hi sdeb,
Great, thanks for that info.
I've had three D8B's in my time. I L-O-V-E-D them. They sound amazing, the EQ's are extremely musical. And as I'm writing this I'm reminded of how much I miss having one. It's a great piece of gear, and it'll greatly enhance your recording experience. You can select between two sets of speakers with independent volume, have hardware faders and pan which is always fantastic, automation, extremely low latency (better than a lot of more recent gear), realtime plugins including EQ, reverb, and so on. And yes, tons of meters! So you won't regret owning one until...
...well, let's consider what it is: it's an 11-year old piece of gear for which Mackie is fast running out of spare parts. And what parts they do have left in their inventory can be very expensive. What I'm getting at is this: unless you're lucky enough to get a really good one, they do have a tendency to fail. That's the reason I've had three of them over the years. And being that you said you're a newbie, it might not be the right thing to start off with.
Let's look at the Apogee for a second...

You have a total of two inputs and two outputs from the Duet (which is your interface). (I'm excluding the Duet's mic inputs for now for reasons which I won't get into atm). Anyway, unless you were tracking bands, or had lots of outboard gear, the D8B is kind of overkill. Now, that's OK, but you won't be getting the most out of it with your current level of gear.
Now, on the positive side, you can use the D8B as a normal mixing board and run its outputs into the Duet. This way you can track yourself live and apply effects in realtime (as opposed to Logic, which can introduce latency) while you're recording. Playback of Logic would be by way of the Duet playing into a set of returns on the Mackie. So that's all fine. But at the end of the day you're going to have this huge piece of gear sitting there running up your electricity bill to act as a 2-in, 2-out mixer.
And as BJ said, as a control surface it's less than ideal. It's fairly incompatible with Logic too. Basically, it's pretty useless in that regard. Trust me, I've tried.
So I hope I've been able to successfully talk you out of this, much as I hate to do it because, as I said, I love that thing.
