The god ray glare is a known issue on vive that I am trying to solve right now. Might be fixed by next update but difficult to tell since I only have riftS to test.
As for moving, it's possible to change the controls through steamVR, check it out to see if everything is set up correctly.
Also, the game starts off in "crouch" position so you need to stand up to move around. Press control on keyboard to see if that's what's causing the problem or not.
