'Course you can DIY that too (same with the oil change).

Dealer/SA are probably getting the M mixed up with the 3.0i or si. The 3.0 doesn't require valve adjustments. Here's a checklist that clearly shows the differences.

The Z4M is relatively rare, and if you put it in terms of it being an E46 M3 they'll probably "get it". But I'm not sure I'd want to trust my car/business to a dealership where I'd have to explain what to have serviced. But if you've got 6K miles to go, you can worry about that later.

I'm not quite sure what's meant by "recording purposes". If you keep all the receipts for work done on the car, and go to sell it, those serve as records. Personally I find those a lot more valuable and accurate than hoping things get reported into "Car Faux", which I've found is horribly (and inaccurate) in some cases.
Inspection I has fluids too. Plugs Inspection II. Valve inspection and adjustment both.

I stand corrected. I'm sure I have an earlier schedule where Transmission and Diff fluids are changed in Inspection I. I'll check when I get home...
