Tikz and geometry package

Question

I am trying to modify the template from this post Grey Sidebar with Article Class & Tikz but I have problems with the title and the blue area. I am not able to modify accordingly to make it shorter or place the title left or right aligned without modify at the same time the introduction paragraph and texts, as seen in the picture:

So everytime I modify the code by changing the top distance is a mess. I attache the code slightly modified from the previous post:

  \begin{minipage}[t]{4.5in} % Mini page taking up 30% of the actual page
   \subsubsection*{US economy will gain strength as 2013 progresses}
   The turbulent political environment that curtailed corporate risk-taking 
    in 2012 will end. Full fiscal cliff will be averted but taxes will rise   
   \newline
    \subsubsection*{Corporate fundamentals support continued profit cycle        expansion}
      We forecast S\&P 500 revenues rise by more than 4\% in 2013 and 2014,   margins hover at current levels (8.8\%-9.0\%), earnings climb by more than 6\% and the P/E multiple expands modestly from 13.2x to 13.8x at end 2013. 
     \newline
    \subsubsection*{Valuation: 12-month target of 1575 reflects 12\% potential   return}
     Our 3-month, 6-month, and 12-month forecasts are 1450, 1500, and 1575. We  use six valuation approaches including DDM, uncertainty-based P/E multiple,  cyclically-adjusted P/E multiple, price/book and ROE relationship. 
  \newline
  \subsubsection*{Strategies to capture growth: market, sectors, stocks}
   (1) Stocks will outperform Treasuries; (2) Equities will beat credit   returns, although not on a risk-adjusted basis; (3) Cyclical sectors will beat defensive sectors (Materials, Industrials, Information Technology will outperform Consumer Staples, Telecom, and Health Care); (4) Double Sharpe Ratio stocks offer both high risk-adjusted earnings growth and prospective returns (Bloomberg ticker: <GSTHEPSR>); and (6) Stocks with high BRICs sales exposure will beat domestic-facing firms (GSTHBRIC).
