Everything looks pretty good, but I think you could skip the initial Klasse AIO step. It seems like overkill to me. I would still get it though as part of your maintenance regimen between polishing. Other than that I think everything looks pretty good.
Like someone else mentioned, Autopia would be a much better place to get your info from. There are much more knowledgeable people there (not saying there aren't any here), than here on NASIOC.
