HELP me decorate my den!

Madison

Okay so I need some serious help.

We bought our house 7 years ago and I really need to make it ours. We have a leather couch and loveseat (no offense to leather but it's not my thing and the upkeep is a turn off) that are torn up, they were DH from when he was single so yeah.

We spend most of our time here so I feel like it needs the most attention. Below are some pics from when we first moved in (none of that stuff is ours so just please ignore).

It is also SUPER DARK at night so I definitely need to add a fan with a light (for some reason the fan was taken out before we moved in). I love the wood paneling and color so I don't want to get rid of it or paint it. The bookcases currently hold our DVDs and DH video games.

Links and/or pics are appreciated.

I'm considering replacing the carpet (it's not tacked down, it is more like a rug) with wood tile as better for allergies. I like neutrals like beige but not 100% sure about gray. Also maybe light blue accents?
