Hey go with motobaridi option, I always use it to recover/reset root passwd for my client servers (ie if I had forgotten them).
Though smt else not mentioned here,u had said u even forgot ur username. Ok easy once in root you can just list home directory and u shall see the users ie ls /home/ . There you shall see the users. Reset all as you see fit. But as warned remember you are full root.
Cram this trick as it will save and come in handy when you administer all servers.
