Flight path vector & autoflight systems questions

I apologise if any of the following have already been mentioned:1. In the cruise, shouldn't the "Flight Path Vector" symbol be level with the Horizon on the PFD (indicating level flight)?2. When the aircraft is climbing in Vnav and passes through10,000 ft, the automatics bring the nose down slightly todecrease the climb rate and allow the aircraft to accelerateto its new climb speed.What is the rate of acceleration that the automatics are attempting to achieve - shouldn't it be roughly 1 knot per second and not the 5 - 6 knots per second at present.I think the autoflight system is being a little to aggressivein it attempt to achieve the new climb speed (at the expenseof the comfort of our virtual passengers !)Fergus
