for the above posts,,,,

you use the same recommended PSI, it doesn't change

yes, you can "top off" or mix the two (air and nitrogen) but for the full value , you should maintain something like 93% nitrogen.

Costco is one of many places starting to offer nitrogen (it's about $10/tire or so) and many tire dealers too. The ads say that some will give "free" refills after you get the first, but I'm not familiar with it.
