Novak HV-Maxx with g2 chassis kit

Hi!
I have all stock E-maxx with HV-Maxx High-Voltage Brushless Motor System, I'm planning on purchasing G3 Race Suspension with g3 race skids, g1 single speed conversion and G2 x-brace chassis kit.
My question is would I be able to install everything without any trouble ? Would it be compatible with my setup ?
Is G2 X-Brace Chassis - Silver Carbon Kit much better than G2 X-Brace Chassis - Carbon Fiber Kit? What is the difference ?
Also, what would you guys recommend I should replace if I'm planning to race my truck , but also I'm thinking about bashing . I want to make it as fast and as bulletproof as possible.
I also would like to know what would be my best batteries choice to fit into G2 X-Brace Chassis , what is everyone else is using ?
Regards,
Jay
