There's usually not much point in changing hubs, as that requires tearing the wheels completely apart - spoke by spoke. and unless the flanges of the new hubs are within mm of the same size the old spokes won't fit. Often cheaper simply to buy new wheels.
But if you insist: remove every spoke from the hub + rim , then lace up the new hubs to the old rim, tension and true.
No. a 9T sprocket will only fit a cassette hub, and not freewheel hubs.
Both Eatern and Haro buys their sprocket from other manufacturers, and the sprockets don't really care what bike they're put on. However, there are two different types of BMX hubs, and sprockets can only be moved between hubs of the same type.
