Two questions:
1) It looks like you have both Office 2007 and Office 2010? Do you want to keep both versions of Office or only have one version installed? (There's no right or wrong answer. It's whatever your needs are)
2) Sony has a lot of crap installed to support their own Media Player. I see you have VLC installed. Can I assume you want to remove everything related to Sony's Media stuff? (As instead, you can use VLC, Windows Media Player, or any other player of your choice)
