This is just because the class has to be defined in =org-latex-classes=
(see the doctring for info).
By default it contains:
 - beamer
 - article
 - report
 - book

This is getting into LaTeX, not Org, but you need to do two things:
 1. Remove indent
 2. Set parskip to the height of a line

i.e.
#+begin_src latex
\setlength{\parindent}{0pt}
\setlength{\parskip}{\baselineskip}
#+end_src

You can add a number before =\baselineskip= to 'stretch' that length.
E.g. for half a line =0.5\baselineskip=.

Hope that helps,
