The car's handling will be affected, though the amount MAY be negligible. This difference will increase the height of the rear end by about 1/4 to 1/2 an inch, and may increase oversteer due to the increased area of the sidewall. I would suggest fitting either the proper sizing per manufacturer or use a proper plus-zero size on all four wheels.

No you can't, otherwise tires can touch fender and cause serious crashes
There is a sticker on the inside of your glove box with pressures listed depending the size of your tires. My tires are 175/70 13 and it suggest 33psi in front and back
175/70r/13
In the rear you can use a 205/70/15 if you have 5 1/5 inch wide wheels, in the front you want to stay with the 145's up to 175's because without power steering it gets difficult to steer with wide tires.
195/70/14 tires are too tall, will rub the bottom of the rear spring mount.
175 65 14 or optional 185 60 15 it will say on the tires
205/60-15 or 175/70-15
Yes, this is an acceptable swap.
