Unless you're adding fruit or something... skip the secondary. It's unneeded, and more risky than beneficial. Actually, it's not really beneficial at all. These kit instructions are no good and really need to be updated.
Go with your first instinct. Gravity tests will lead the way. Don't bother checking them for at least a week.
Also, it's been less than a week. Have patience. Airlock activity is not a sign of fermentation process. Your initial fermentation is probably complete, so give the little guys time to clean up after themselves.
I always let my ales sit in the primary for at least 2-3 weeks... or until I figure out what I'm going to do with it (bottle/keg). Sometimes I'll leave it for months, 'cus I'm lazy! No ill effects if it sits on the trub for a while. Basically, you have all the time in the world to make a good beer (just try to keep it under a year).
Now don't start going crazy and putting different crap in it or taking samples every few hours. Leave it the hell alone and let it do it's thing. I understand it's your first beer, but playing with it is going to make it your first infected beer. That's not fun.
Beer brewing is the great teacher of patience. Learn and enjoy!
Good luck with your new hobby!!!
