The pros/cons of nitrogen has been discussed at length in previous discussion on this forum, but I don't recall seeing anything about -
Where/how can I inflate beyond sidewall max using nitrogen.
I suggest you start a new thread in EcoModding Central using the above as a title.
Don't bother with the dealer. If you have an air compressor, use it to fill up your tires. Otherwise, find a gas station with an air compressor and use that.

As far as how much pressure to use, I'm currently running both my cars at 50 PSI. I gradually worked up to 50, first running 35, then 42, then 48, and now 50. The ride is a little rough, but it's getting great MPG numbers.

Check out this thread for lots of comments on personal experience with tire pressure:

How many PSI do you run in YOUR tires?
