Hi Spelunx
Sorry for being vague you get used to talking to blokes on site who are used to my ways....
To brace the poles i'd use 4x2 or 4x3 run on the diagonal from the bottom of the pole near your concrete up to the top of the pole .... On one side do both ways (crisscross)and the others one way might be enough.... what you aiming to achieve is that your poles are almost as stable as when the deck is finished this way you won't disturb the footings and once you plumb your poles you'll be confident they stay that way.....
As for pre prep you cut.... sort ....measure ....seal ...anything that can be done now so that you don't get slowed down once you start construction.... Also take the time now to figure out as many problems you think you might have so they are solved before you get to them...
Hopefully your not like me and do it whilst your sleeping cause i reckon i build every deck atleast 3 times 2 whilst asleep and once on the job
I expect to see photo's of the finished result soon!!!!
