My advice: don't sweat minor inaccuracies, like a wrinkle in the covering. Perfection isn't required and building skills come as you build kits one after another. Each one will turn out a little better than the last.
I've noticed if I build the fuselage first there's no telling how long it'll take to build the rest! On the other hand, if I get the wings and tail surfaces done first the whole project continues quickly.
I mark each piece with its part number while still in the die-cut sheet according to the diagram provided.
A 4-Star airplane is going to be a great reward for your efforts!
