You will probably need to rotate the fork & then secure the stem bolts, fit the saddle (apply grease to seatpost), pedals (apply grease/anti-seize to threads & make sure you get them right way round - thread is different left to right). All should be do-able with a decent set of allen keys. A torque wrench would be ideal but not essentail as long as you don't go mad raunching things up. Apply a bit of grease to the wheel quick release skewers as well. Look online for videos to help if not sure - plenty of them
