That's a link to my resume. It's not updated for my current job, but the format has been the same for ages. Yes, you can omit things like Salary Requirements and References as it is assumed they are Negotiable and available upon request, respectively, however they are nice touches.
Don't overdo it with details that don't pertain to the job you are applying for. If you want to be my new IT Security Engineer and you put a lot about how you can file papers and perform office tasks, I won't hire you.
Tailor the resume to either each position you are applying for, or specific to the job you want. This allows for optimal details within the 2 pages without going overboard.
