Doors
They still might (open). It is not a problem. Slow down, land a relatch the door. I have had it happen a couple of times. The problem stems from not making absolutely sure the door is properly latched in the first place, in particular dont leave it to thd pax.
Flying
There is nothing about the 20 that is difficult. Some struggle a bit with the speeds and staying ahead of the aircraft. If you do you just may not be a "natural" and will have to accept it takes longer. There is nothing unusual about the stall (it is all myth) and the accident rate is not exceptional (another myth).
Get some good instruction and you will be fine.
A and c makes a valid point.
