comment What could be causing my AFCI to trip?
@Dave The AFCI receptacle only protects the receptacles on the device, and anything supplied by the LOAD side terminals.

I made some notes on your diagram, that you may or may not find helpful.

comment Why does a subpanel need separate ground and neutral?
@ratchetfreak prevent what, the current on the grounding conductor? No. The grounding and grounded conductors are bonded at the main panel. If they're also bonded at a second panel, any current on the grounded conductors of the panels branch circuits will use both the grounded and grounding conductor to return to the main panel. A GFCI breaker in the main panel on the feeder to the second panel, shoulda/woulda/coulda trip if the grounded and grounding conductors are boned at the second panel. This is because some of the current will be returning on the grounding conductor.

If the second panel is in a seperate building, the main breaker satisfies the disconnect requirement.

comment Why does a subpanel need separate ground and neutral?
If you have the grounding and grounded (neutral) bonded at the second panel, you will have current on the grounding conductor. If for any reason the grounded (neutral) drops out, all the current will be on the grounding conductor.

comment Can I cap the air return in my unfinished basement?
You might try installing a damper, and restricting the air rather that completely closing it off. This also leaves you the option to reopen the duct if you notice any problems. You'll want to monitor the furnace for overheating, and not ignore any high limit trips.

Do you feel that this configuration is causing any problems? Is the rest of the home not warm/cool enough?

The basement should be conditioned space, so there should be no problem drawing air from it. You'll want to make sure you change your filters often though, since basements tend to be dusty places.

This is impossible to answer definitively, without a comprehensive inspection of the system.

comment Why would changing ceiling fan speed cause an AFCI breaker to trip?
Not sure what the internal circuitry of one of those switches looks like, so it's difficult to say for sure what's happening. When switches are opened/closed, there's a tiny spark that's produced. AFCI breakers know about this, and can ignore it. If you take a long time to move the switch far enough to break the arc, it's possible that the AFCI could call that an unsafe arc and trip. It's possible that holding the switch between states maintains an arc, which the AFCI does not like.
