Addt'l Work w/ M104 Head Gasket?

I have a 1996 E320 (M104) with an oil leak at the right rear head gasket. The car has 99,600 miles. I think that this will be a DIY head gasket replacement. My question is what other work should be done if I am going to remove the head? The items noted in prior posts include 1) complete valve job including replacement of guides and seals, and 2) replace tensioner and guide rails for timing chain (but not chain itself), and 3) replace rear heater hoses (how are these parts identified on FastLane?). I think that the 1996 has the updated EGR pipe already in place.

As part of the process I understand that I will need new head bolts and washers.

Does this list seem reasonable?
