I ran mine from one end of the house to the other - about 45', give or take. You shouldn't have to leave breaks under doors.
You may or may not have to use the 1/4 round, depending on how much of a space you leave between the wall and the end of the board with the largest gap.
On some styles of baseboard, the 1/4 round gives it a finished look anyway. I ended up not having to put any down with my baseboard, but it doesn't look quite right. I'll probably add some anyway (some day).
