The best advice I can give you is: watch your baby. See when your baby gets sleepy/tired, make sure you prepare the environment so that it's conducive to sleep, and record it on paper. This also counts for daytime naps. By around three months of age (sometimes a little later) you'll see a definite pattern in baby's own biological clock.
Based on what you find, you can then work your routine around it.
At nine weeks he's probably still too young for you to notice a definite sleeping pattern, but I would just put him to bed whenever he's sleepy (watch for head-bobbing, yawns, fussiness, rubbing eyes).
My baby happens to have the same sleeping pattern that I do -- goes to bed at 11 p.m., wakes up at 9 a.m. Most likely that will change in the near future, with school and all.
Good luck!
