Paint Color Paralysis

I was pretty confident in my color selections a couple of months ago, but I realize now that I made a rookie mistake.  I didn't live with the colors on the wall first.  Paint chips only tell a very small part of the story, not to mention the changes in light from room to room and time of day.  The dining room and living room were in my mind a soothing blue gray color, the dining room a slightly deeper shade then the living room.  I am afraid that the rooms will be a bit cold with the cool blue tones, but really want something that will compliment the rich floors which I thought that tone would do well. 

So, I went and got samples (under $3 a piece at Home Depot), lots of samples.  I have applied them to the walls in each room to live with for awhile.  I also grabbed a few warmer shades in the yellow family to see if I prefer a warmer wall color.  Here is where we are at - your thoughts and opinions are very welcome!

Dining Room Back Wall - My blue/gray selections. 

Dining Room Side wall under stairway (ignore the clutter - still unpacking!)

Living Room - Warm and Cool Palette

Living Room - Warm and Cool with Deeper Accent Colors
that will be used in a special project involving book cases

My initial thoughts are that the yellow colors too similar to our furniture color and there won't be enough contrast in the room.  I'm thinking that the warmer fabrics will offset the cooler wall color if we stick with the blue tone.  As a side note, that horrible trim color is getting painted a white semi gloss.  You can see where I started around the door frame.
