Spark Plug Change Questions

I just purchased the Bentley manual and it references putting the hood in "service position" before removing the cowl above the engine to access the engine cover and eventually the spark plugs. The manual also references some special BMW part (51 2 170) that you need to raise the hood to service position. Is this necessary? None of the stuff that I've read here or anywhere else on the internet as a DIY manual references raising the hood to service position.

Also, one is not supposed to use anti-seize or silicon when doing the spark plug change, right?
