I have a USB audio interface which I use for recording. When I use some recording app (like Audacity), I can select the USB interface from a drop down menu, which will tell Audacity to use that device for audio input.
Sometimes I want to record from that device, and also add voice-over using my computer's internal microphone. I cannot record from more than one device simultaneously using Audacity (as far as I know), so I'm looking for a program to mix the inputs first.
I have the Soundflower driver installed, so all I need is a program where I can select both my USB interface and my internal microphone for input, and select the Soundflower device for output. That way, I can select the Soundflower device as input in Audacity to record the pre-mixed audio.
Is there such a program, and am I on the right track (no pun intended)?

I have a similar need when recording Skype calls. My setup is somewhat different, but the fundamentals should work for your setup. Best of all, you can do it without buying any specialized applications. Rogue Amoeba has a great application called Line In that will allow you to pipe your system's inputs to whatever outputs you are available, including Soundflower.
Go to System Preferences -> Sound:
Start Soundflower.
This will bring up the Audio MIDI setup application. From here, you'll create an "Aggregate Device," which is accomplished by clicking the
+
icon in the lower-lefthand corner.Start Line In:
Finally, fire up Audacity, and make sure Soundflower is selected as the input. This should create a chain that ultimately pipes your inputs into Audacity.
I hope this helps, and good luck!
