I think there might be a problem in your voltage feedback circuit. Take a look at p9 of the datasheet. Your missing a ground connection.

No the current limit resistor should be higher in your application, I would start with 0.05R-0.1R, this is good for 10A to 5A (0.01R is for 50A) wich is high enough for you at the moment, the chip will go in protection at 0.5V, make sure you use something like 1n4007 for d1-d4 to handle the voltage.

Those capacitors will work, as close to your mosfet bridge as possible, an extra small value (a few uF) capacitor parallel with low esr/esl like mkp is advisable.
