Answer 1

Since you are using \fbox, you have to change the widths. Also add few % at end of lines. Further, use valign=T. Hence we have,

\block{Text and figure Block using MINIPAGE and MULTICOLS}{
  \fbox{%
  \begin{minipage}[t]{\dimexpr0.7\linewidth-2\fboxsep-2\fboxrule\relax}
  \noindent
  \begin{multicols*}{2}
    \lipsum[1]
  \end{multicols*}
  \end{minipage}%
  }%
  %
  \fbox{%
  \begin{adjustbox}{valign=T}
  \fbox{%
  \begin{minipage}{\dimexpr0.3\linewidth-4\fboxsep-4\fboxrule\relax}
    \input{./myDummyPictureCode.tex}
  \end{minipage}
  }%
  \end{adjustbox}%
  }%
}
