Good Questions: The Best Way to Unite this Room?

I have a whole mess of questions for you. I've attached two photos; one of each side of my living room. To look at the photos you might think it is two different houses! First of all, I want to find a way of marrying the two sides... perhaps using a large, central coffee table? I would love to have an oversized piece that was short enough for guests to sit around on the floor when we entertain...

Photo 1: What is the best way to "marry" the two sides of this living room?
Photo 2: Once upon a time I worked at an auction house in Scotland. That is where I got the Rococo mirror and the tiny kripie stool. The yellow jaquard sofa is from my grandmother's old home in Charleston, SC. I would rather not talk about the two chairs. Suffice it to say I am waiting for slipcovers.
Photo 3: I want to paint the mid-century table a punchy color. Yellow, perhaps? Or is there too much color as it is?
Overall: I cannot believe I am allowing anyone to see our hideous wall-to-wall carpet. It's enough to drive me to drink.
Please help.

A quick solution we noticed right away — switch the ornate mirror with the graphic calendar. By mixing the entire contents and not relegating different styles to sides of the room, it will instantly look more pulled together. Anyone else?
