I would say the service is sub-par at Acura North Toronto and Erin Mills Acura (although the tech at Erin Mills knows his stuff with the NSX, and he's the only one I trust to do anything with my CTSC).
I've had relatively good experiences with Woodbine Acura and Sherway Acura, although the service manager at Woodbine recently left and I'm not sure how it is now.
For alignment, I would go to an alignment specialist like Woodbridge Alignment, which is close to Weston + Hwy 7. It looks like a real hole, but it will be cheaper and they'll do a better job than the dealership (in my opinion). You'll also be in and out faster. It's also pretty much your only option if you have a really lowered car, as they use a pit instead of a lift.
For iPod vs Trunk CD Changer, I'd visit the Stereo forum here on Prime, and post on there. People here are WAAAAAY more knowledgable about this stuff than anyone at a dealership will be. Most dealerships will be lucky if they see a few NSX's a year. Another option is to visit a dedicated Audio shop, and talk to them about it.
Install daytime running lights: If you want to save some money, I would go to an independant such as Ken @ IPC 905-791-2277. Get a quote from both and then decide. Although I suspect with your current stable, cost is not as big an issue as convenience
I'm all in favour of building a good relationship with a dealership (and I have with two of them), but at the same time I hate getting ripped off which is something that dearlships seem to excel at. eg. if you're getting new tires for your car... go to a tire place, don't go to your dealership unless you know them really well and they are giving you an awesome deal. eg. my last set of tires I was quoted $100 more per tire by the dealership.
