I'm still at 1.0g, and 300kts, but I'm in a decent, obviously angle of attack is less than in level flight.
This is a common misconception, but is not true. The angle of attack does not care if you are in level flight, climbing, or descending. As long as you are in unaccelerated flight, the AoA is identical.
It's not exactly the same, because if the descent (or climb) angle is significant, the lift only has to supply part of the weight of the airplane (the rest being supplied by drag or thrust), so the AoA will be slightly less. But that's accounted for because the load factor will also be slightly <1G.
(The edge case is if the plane is flying straight up or down. In that situation, the wings provide no lift at all and the AoA will be zero.)
