Considering attempting this procedure this weekend for my 335i. Just to summarize it is recommended that I drain the coolant (

The N54 follows the same procedure for the coolant draining but has a more involved gasket change due to the manifold differences from the N52 (Correct?). As a result I should go ahead and change the manifold gasket as well.
Parts:
Oil Gasket (part 11427537293)
Oil Filter (includes orings)
7 Quarts of BWM synthetic (or Mobil 1) 5W30
BMW Coolant (2 Gallons)
Manifold Gasket (Part ????)
Is there any gasket needed in the coolant draining procedure? What is the part number of the manifold gasket? I want do this right so please if there is something I need to be aware of for my car please let me know. I am not interested in the short way but rather the correct way.
Also my oil leak is quite substantial so what are the trouble shooting procedures to ensure successful completion? Just clean everything up and see if it leaks again? There was mention of applying grease to particular locations in an effort to eliminate possible sources of leaks. Can someone be more specific as to those locations?
