Help redecorating my Living Room #1

HI! I decided to start improving my room / redecorate my room, after I have been living in a bit of a mess. I'm still in army (one point eight years ~ so far) and I still have a year left. That means I'm not much in my room. After Army, which is a year and a couple of months more, I am planning to still live with my parents for a couple of more years (working and studying).
That means I need a steady, clean, decorated and stylish (or unique?) room to feel comfortable in. In this I'm now starting this project, which hopefully will consist of a couple of more journals in the future, with pictures of before and after. It should take a couple of weeks to months, until I get the right satisfaction.

So now - I still haven't made a picture of my room yet, but I'm hoping in this journal to get introduction to sites, ideas, items, areas that can improve the room. Anything that you used to improve or decorate your room, advices and so on.

So far I though of:
Drawing / painting on the wall
Buying decorative pillows
Buying a 'smell' perfumes decorations ( those you burn and they provide nice smell)
A small carpet
Poster / picture.

Also, if you have any great deals from eBay where I can buy interesting items, I'd love to.. I tried looking at eBay but I was a bit lost as I couldn't find which category to look at.

Pictures in the next journal!!!
