In theory, I think the OP's comments are fair; if you are paying that much for a meal, it should be exactly how you want it. Were I the owner of a fine restaurant, I'd want my customers giving me instructions like that to ensure that they enjoy their meal. It's important because, as another poster said, every place is quite different and some of the things the OP finds disagreeable are things other customers might want/expect.
That being said, my only curiousity is whether or not they take these comments seriously. Aside from places where you are a regular or where (as matt mentions) they know your routines, I'd say they couldn't care less, and probably roll their eyes.... assuming they even read them. I tend to be a person of routines in any case, but a small place that knows how I like things is far better than a big "famous" place where I have to send an e-card to get them to provide the service I want. Sure, their sea bass may not be as great, but it's worth it if I don't have to listen to some asshat chatting about his cream sauce like he's just figured out the Rosetta stone.
"As a gentleman of rather specific tastes, I request a table placed slightly away from other customers, wherein I can be served in the nude."
I actually disagree. The point of a restaurant experience is to have the meal the way THEY want it. They have chosen the decor, the ambience, the chef, servers, flatware... etc. You are allowed preferences... where to sit, what to order.
If you want what the OP has stated you should hire a chef to serve you at home. THEN you can have EXACTLY what you want.
