You should consider your resume, cover letter, and their fit with the position before anything else. While it can be tempting to apply to a large number of jobs, you should concentrate on the ones you're most likely to land. Positions outside of your skill set or well above your abilities are unlikely to call you for an interview.
Make sure you are adapting your resume and cover letter to every job for which you apply. Hiring managers generally weed out applications that look like prefinished forms. By customizing your materials, you show effort and more interest in the job.
Unless specifically directed not to, you should follow up with hiring managers after a week if you haven't received a response. This is a simple call or email where you reiterate interest in the position and ask if they need any additional information. Whether you receive a response or not, you have improved your chances of getting an interview.
