Answer 1

no, projecting to a darker color like in gray will enhance the contrast and how you see the blacks. but if you have a good contras ratio and good control of the light environment you will be good in white.

Answer 2

Yes.  An off-white wall or even a flat white painted wall will not reflect the projected image as much as a semi-gloss white.

If your projector is under-powered (lumens-measure of brightness) then a properly reflective screen is a must.

A screen with a 1.3 db gain is often referred to as ideal for home theaters.
