Second all that Seamus said. Also, slowly increase aileron and rudder input in the roundout and flare. This helps as your control effectiveness decreases as your airspeed decreases so you don't drift. To prepare for your solo (and any/all flights doing new stuff), chair-fly. Put yourself at the airplane mentally, have your notes and checklist with you and go through every part of the flight from the walk-around to when you get out after engine shutdown . Be as detailed as possible, talk yourself through each action. (Radio calls, turn to HDG XXX, set power to X rpm, etc) Good luck and don't forget to have fun!
