Another vote from everyone else's advice. Read ahead, fit everything together with clecos, make sure you see how all the parts fit together before you rivet anything. Maybe not so much in the tail, but later on you'll see why certain rivets have to be flat-head, countersunk on a certain side, etc - because they sit underneath another part.
And when they tell you to weigh everything down on the rudder and elevators when drilling the trailing edge, they mean it! Had to rebuild an elevator because the trailing edge was so screwed up. Rites of passage.
Go and buy yourself some of those organizing containers from Lowes or Target, and dump your various rivets, screws, bolts, etc into each one, labeled appropriately.
Otherwise, enjoy, take your time, and KEEP DOING SOMETHING. I try to do something, whether it's just drilling a part, just deburring, etc each night. It keeps things moving, and keeps the relatively "big" picture of how those parts go together fresh in my mind. The times where I've had to take a few weeks or a month off from building because I'm busy elsewhere is when I find I need a few nights of "ramp up / refresher" time to remember where I was, how things went together, etc.
