This is a "scrub & wear" rug.  You can't hurt it.  The various colors of grey/shading and ivory gives it depth.  Yes, you should use a rug grip with it, as it is thinner.  (I say 'rug grip' as these are made out of recycled grey dense rough foam and rubber on the other side.  This is really the only interior rug pad/rug grip you should buy.  We have been using them for years!
