Here are some photos of the living room

Place your sofa in the middle of your floor facing the wall with the small window and tv. Place your chair opposite the tv by the big window, but face it at an angle looking at the tv. Place one end table to the right side of the chair.
Move the love seat to another room. You are trying to put too much furniture in one room.

No, you have a whole wall for your TV. And since you have nothing else in the room like a fireplace, that's it's proper place where it will be your focal point. Get a media cabinet that's about twice as long as the TV, center it on that wall, center the rug on the media cabinet, place the sofa and chair so their front feet are on the rug.

Start there. Then we can talk about the rest of the space.

Thank you both so much for your help! I'm unable to put the tv on that wall because it's an older house so the cable jacks are only along that one wall where the TV was originally. I didn't want to purchase another media center bc we already had one. I ended up doing what Finishing Touches suggested-saved me money and a headache! :) Thank you so much for your input, I really appreciate it!

jennifer, is your house older than 1910? Because that's how old my house is and I have cable jacks pretty much everywhere on interior walls. Which is actually pretty funny because I don't watch TV. My point is, it can be done. But I'm glad you solved the problem without too much expense. ;-)
