Star Wars comics can be canon. They're part of the larger Star Wars narrative. But it's important to note that the determination of canon can change over time and based on the decisions of the Lucasfilm Story Group.
Sure. There are several Star Wars comics that are considered canonical. They contribute to the overall lore and add depth to the franchise. Some of them explore events and characters not covered in the movies or TV shows.

Writing Star Wars comics involves a lot of research. Study the existing movies, TV shows, and other comic series. Focus on creating characters that are both familiar and fresh. And make sure your story has a balance of action, adventure, and emotional depth that makes it truly Star Wars.
