1) Yes it is possible but you are better off bulking hard if you are a beginner, a little fat gained is ok you can cut later once you have a respectable muscle base
2) Nothing wrong with protein shakes very good way to quickly get 30-40g of protein, highly recommended. As for other supplements creatine is recommended but not required.
3) bulking - eat more calories than your body uses. Cutting - eat less calories than your body uses. A good starting point is going 500 calories over (or under if cutting) and adjusting from there after some weeks
hope that helps, if youd like more specific information this guy is a professional and would be happy to answer your questions for free:
