algorithm2e: How to define my own macros? +2

Question

Just starting to play around with the algorithm2e package and I have difficulties to figure out the things I need.

Here is my minimal working example:

\documentclass[10pt,a4paper]{article}
\usepackage[lined,boxed,commentsnumbered,german]{algorithm2e}
\begin{document}
\begin{algorithm}
\ForAll{$i\in \left[n\right]$ in parallel}{
    $a\leftarrow b$\;
}    
\textbf{repeat} $\left\lceil\log n \right\rceil$ \textbf{times}\;\Indp{
\If{$b > 1$}{
    $b\leftarrow c$
}}
\end{algorithm}
\end{document}

which gives me this:

1. Instead of 'forall the' I would prefer to have just 'for all'. Instead of 'in parallel do' I would prefer to have it together as 'in parallel do'. How do I achieve that?
2. How do I define my own macro 'repeat', so that is has an 'end'-statement, 'times' is inserted and a working vertical line at the left border?
3. Is it possible to remove the 'end' of the 'if'-statement? 'lIf' is neat, but not really what I am looking for..

I tried to understand the documentation and the threads here on stackexchange, but the examples are quite complicated for a beginner, so I would be grateful for any advice.

Thanks in advance!

A first version, not complete so far!

The \SetKwX macros define much of the keywords and appearance style, but not all is possible, apparently, without manual interaction on the precise position when the \ForAll etc. statements are used.

\documentclass[10pt,a4paper]{article}
\usepackage[lined,boxed,commentsnumbered,german]{algorithm2e}

\SetKwFor{ForAll}{for all}{do}{end}
\SetKwRepeat{Repeat}{repeat}{end}
%\SetKwIF{If}{ElseIf}{Else}{if}{then}{else if}{else}{}
\begin{document}
\begin{algorithm}
\ForAll{$i\in \left[n\right]$ in parallel}{
    $a\leftarrow b$\;
}    
\Repeat($\left\lceil\log n \right\rceil$ times){}{%
  \lIf{$b > 1$}{\\
    $b\leftarrow c$
  }
}
\end{algorithm}
\end{document}
