DRV8332: Resistors at the application diagram

Part Number:DRV8332

Hello,

I am newbie at motor drivers,

I want to design BLDC driver via 8332.

I checked the application diagram at the data sheet. 

I need help about resistors. 

There is a 3.3 ohm resistor at PVDD source

and 

There is a 1 ohm resistor between AGND and GND

What are the purpose of these resistors and which package(watt) should i use?

I am going to supply 48V.

Motor RMS 6A

Motor Peak 9A

resistor watt of 3.3 ohm PVDD = V2/R = 48*48/3,3 = 698W???

And one more question:

https://katalog.we-online.de/pbs/datasheet/742792903.pdf

Is this ferrite bead suitable for my design. In the datasheet, it says "10 ohm or higher at 10mhz or below". It looks suitable but I want to be sure.
