Basic changes to my wordpress site

I need some very simple changes done ## Deliverables I have a wordpress site here: [login to view URL] I have two simple changes that I don't know how to do. Firstly I would like to move the sidebar closer to the actual posts. Secondly I want sidebar titles similar to [login to view URL] However instead of white text on beige background, I'm looking for white text on blue background. I don't know exactly what I need to do but am technical enough to follow all instructions. There is no access to the server you simply need to instruct me what to do. This should be a very quick and hence very small project
