Manvisudan, choosing a rug more along the lines of what I showed will afford you the opportunity to add some fun and interesting pillows to your silver ones. Its easy to change your pillows when you want a different look. The rug, on the other hand, is a bit more of an investment. Let me know if you would like pillow and art recommendations :)

At first glance I think that if you are going for a modern look, I would suggest nesting tables instead of a coffee table to create interest. Here are a few ideas for you: http://deciture.com/the-amazing-set-of-3-wood-nesting-table/ http://deciture.com/gilbert-galvanized-nesting-tables-set-of-3/ http://deciture.com/flouressa-mirror-top-nesting-tables-set-of-3/ http://deciture.com/brighton-mirror-top-nesting-tables-set-of-3/ Hope this helps you!

I think your inclination toward rustic and distressed pieces is the right way to go. Consider a movable coffee table - I see 2 recliners that may necessitate some table shifting?- an area rug large enough to incorporate all the seating, rather than just a hearth rug, and enclosed storage for your electronics. If you can post shots of the room, other Houzers may have some more ideas.

The recommended fit around a DR table is 24" larger on all sides for the chairs. You won't have that on the 6'8" side. I'm thinking the rug is going to be too small for the room 8x10 or even 9x12 would have been a better choice.
