I'm not familiar with the VR6, since I own the 4-cylinder version (same year). My manual also specifically does not cover the VR6, just the 4's.
You said from the "well established vw enthusiast web site" they list the many-step process, but not where you found the quick, down and dirty process. Going on that alone, it sounds like you don't trust the short procedure you found.
In my dealings with this car, I've come to understand that many of the things they say I must do (remove this many parts, whatever), I can very often perform the maintenance I need to do without removing everything they say to remove. Having said that, even though my hands aren't particularly small, I am pretty agile, have a huge selection of tools, and can typically find a way to get into those areas I shouldn't be able to.
When I did my belt/water pump, I didn't have to remove anything, except the motor mount they had the brilliant idea to mount in the middle of the belt path. It was tight, to be sure, but I got it done.
I would be hesitant to remove all those things, but the "force it down" procedure doesn't sound too kosher to me, either. Probably somewhere in the middle may work. I would also use caution when pushing and pulling on the motor, as there are so many lines to consider, and I wouldn't want to have to fix those, just because I was too lazy to remove part X.
Have you considered using blocks and/or tranny jacks to support the motor, then disconnect the motor mounts, and get that inch of space? It might be enough. If you have the replacement pump in hand, you should be able to figure out how much space you really need.
