I started using a clicker when I was shown the light 18 years ago. Since then, every Border Collie I have trained, and every dog that has passed through our clubs obedience and agility training classes, has been trained with a clicker. Positive training methods are, to my mind, superior to the old style yank and crank choker chain. You need to find an obedience club, or a club that holds puppy obedience classes, and trains using positive methods. The socialising with other young dogs is really important for your pup, and the instructors will be able to show you how it all comes together.
Dogs do learn off each other so you may find some undesirable actions rubbing off from your Maltese but you can extinguish those behaviours by rewarding him when he chooses your way instead of the Maltese way.
