I find the M-rgrep command very useful but need it frequently in the

parameters and only asks for the search pattern (the project-specific
parameters have already been assigned to some variables) ?

You just need to write a few small lines of lisp.  Read the
documentation for rgrep:

C-h f rgrep

I did, but I am new to Emacs customization and might have overlooked something.
If I do the equivalent of a

(setq grep-find-command "find somepath \\( -path \*/.svn \\) -prune -o -type f \\( -iname \\*.cpp \\) -exec grep -nH -e {} /dev/null \\;")

in my .emacs file,
C-u C-u M-x rgrep
does indeed use this pattern (and does not ask about anything else, and I could use a keyboard shortcut for this) - so far so good. However, I feel that having to look at that long-ish command every time I use it, is not elegant - in particular, as I need to navigate to the correct position when the find command is being displayed in the minibuffer (point should be between "-e" and "{}" to insert the pattern to search for). Could you help me improve on this?
