You can sneak into good seats if you know where vacancies are. However, during Ladies Free skate, there will be no vacancies, and Men's Free Skate, there wont be much. It's easy to meet new people in the area you are sitting and exchange views on skating.

Maybe you can, maybe you can't. I've never actually been to a Nationals, but based on my Worlds experience (Vancouver '01), depending on how gung-ho the ushers are, they may not let you move. Not that there were any empty seats available at any point in Vancouver anyway during the competition, but, at least where I was sitting, those ushers were pretty hard-nosed about making sure you sat where you were supposed to.
DEFINITELY dress warm. Of course, Portland in January, you're pretty much going to be doing that anyway (I lived there for 6 years, believe me, I KNOW!!

) I spent the entire week at the Worlds wearing a very heavy turtleneck sweater and a jacket because the sweater was the only thing I wasn't shivering in. Actually, the Rose Garden, which is where I believe the Nats are going to be, is a larger arena than GM Palace in Vancouver, so it will probably be even colder there. Practice sessions are going to be a bit colder, because there's less people around and therefore less body heat floating around, plus (see next paragraph) you'll be closer to the actual ice surface.
As for meeting the skaters, what I reccomend is, find out where Kiss N Cry is and park yourself as close as you can to it during practice sessions. This of course is where the skaters will come off the ice at the end of the session and if my experience is any indication, they will be signing autographs on their way off the ice for all the other people sitting in that general area. I wish I had discovered this trick much earlier in the week in Vancouver; had it not been for a couple of very nice Canadian ladies I met on the evening of the last dance practice, it never would have occured to me.
If you're going to be sitting in or near the rafters, pack binoculars. This actually isn't a bad idea regardless of how good your seats are. You can get a close-up view of the action, plus during down time (rink resurfacing, etc.) it can be very entertaining. In Vancouver, I happened upon the sight of Elvis Stojko making out with his girlfriend in or near the CBC booth.
