Stations don´t have an area of effect in this game. Instead, the game calculates the time necessary to go from a to b. Build your stations like in real life. When you take the bus to the train station, you will curse the planner to hell and back if you need to walk 2 miles in between the two.
Can´t help your with your second question, sorry.
