It could be me but I don't see the difference between #11 and #13, both are connected correctly.
Regarding the diodes, with no PWM nearly anything will work. The current rating should be at least what two motors will draw.
Regarding the 220 gate resistor. While the idea that lower resistance will switch the FET faster is absolutely correct. With your FET (very high current capability) and the motor (likely not too much current drawn) the gate resistor is not critical. I add this to give you a sense of the relative importance of different design decisions.
Just to mention the importance of good ground routing. Your design will work, however you will find as you progress into more demanding designs that how you run the grounds becomes more and more important. Once you get this going and are more familiar with the components, you might want to change the layout so the grounds are as nearly at one point as you can. In designs which require fast switching of moderate to high currents, lead length is your enemy.
You might also want to add some capacitance from + to - on your proto board. Perhaps a 10 to 50 µf and a 0.1 µf in parallel.
