Foremost knowledge of the objectives and strategy of the organization then check out the job tasks and acquaintance with colleagues

Know the stake holders.  understand the organization. understand your roles,  understand the importance of your contribution to the organization. understand where do you stand in the organization chart, who is your immediate superior to whom you will be reporting, who are your peers and subordinates, speak to them, know the expectations, know what you are supposed to do and what not.  do not make the mistake of trying to become a superman at the workplace at first entry. start slowly, understand the systems and procedures well, contribute steadily and constantly.  understand the culture, adapt yourself to the culture, be open to discuss issues with your peers and superiors.

know my colleague and watch them and all things around me carefully

My first step would be to get introduced with the collegue / staff members then study the business philosphy of the company along with study of policy / procedure documents. 

Starting at a new job can be nerve-wracking, because you have new tasks to learn, new bosses to impress and new colleagues to meet. It's important to know how to behave at a new job to make a good first impression. Keep in mind how to behave at a new job so you can succeed in your career.

Take the time to introduce yourself in the elevator or to colleagues at the desks across from yours. Engage your new coworkers in conversation when they welcome you to the team, but stay neutral in your opinions about them. You don't have to automatically be seen as a "cool" person by your new coworkers, so act natural and be yourself. It's a new job and there's a lot to learn, but don't let it intimidate you. Remember you earned that job due to your experience and let your workplace attitude display that confidence and experience. You're a new employee, but you're part of a team. The sooner you start acting like it the sooner you'll be accepted as a team player. Ask your manager or superior what you can be doing to help the team.
