Answer 1

Several problems:
\location is not defined. You must either define it or not use it. Ignoring the error messages is not an option
In this particular documentclass \paragraph is not defined. You must either define it or not use it. Ignoring the error messages is not an option
If you don't supply the required information, you must not use \makecvtitle. In particular an empty address causes an error message. Ignoring the error messages is not an option
to remove the dotted lines in the subsections you can use \renewcommand*{\subsectionrule}{}
the \vspace*{-12mm} in the preamble does nothing useful
\documentclass[11pt,a4paper,roman]{moderncv}
% possible options include font size ('10pt', '11pt' and '12pt'), paper size ('a4paper', 'letterpaper', 'a5paper', 'legalpaper', 'executivepaper' and 'landscape') and font family ('sans' and 'roman')
% modern themes
\moderncvstyle{banking}
\moderncvcolor{black}
% color options 'blue' (default), 'orange', 'green', 'red', 'purple', 'grey' and 'black'
