Drywall is heavy, so 1x2 might be on the small side, I prefer 2x4, but furring strips may be OK. As for a how-to, not sure of a link. Tops get nailed/screwed to the house framing, either directly into a joist, or a bridge between the joists. Not a bad idea to insulate that duct, also.

If you decide to use the 1x2 or 1x4's, attach your verticals to a substantial strata above, but on the bottom chord, don't attach it with fasteners facing "up". Make it to where you drive your screws sideways. This will give more vertical support for the frame. Place them on at a minimum of 16" oc and attach your drywall. If possible, and if you can find it, use 3/8" sheetrock. It is lighter and won't put as much strain on the boxing. I am like Bill, I prefer a beefier support system, but understand space considerations as well.

I always build my soffits with 1/4inch plywood/OSB and 2X2's for framing - then drywall over that.
