NASA lights humongous rocket that goes nowhere ... until 2019

"Won't 8 million pounds of thrust also knock Earth out of it's current orbit and crash us into the moon?"

There will be a minuscule effect on the Earth, every force having an equal and opposite reaction and all that stuff but the Earth is very big and very very heavy when compared to a rocket so I really wouldn't worry about it.

Anyway the Moon is receding so any change to the Earth's orbit won't be enough to catch the Moon. also as the Moon orbits the Earth if the Earth's orbit was disturbed the Moon would just tag along for the ride staying in much the same orbit as now.
