"You are technically correct, the best kind of correct."
Some may call it 'decelerating' for the second half, but in physics this also counts as accelerating (just in the opposite direction).
22 mph = 35 kph = 9.8 m/s = 33 ft/s

Pretty much. The Earth-Mars transit would be 2-5 days, depends on planetary alignment, and also how close your ship can get to the Sun without overheating.
For Pluto it's about 18 days.
The simplified equation to calculate travel time is 2 × sqrt(distance / acceleration)

Yes, going ~850 km/s is not feasible today because we don't have torch drives like in The Expanse.
Torch drive / torchship is the generic term for the idea, an idea which has been used in various works of sci-fi. See more:
