Cover letters should include:
Which position you are applying for
A summary of your key skills & qualifications
An explanation as to why you have chosen the company & position

Resumes should:
Be created for each application
Clearly state your education information- type of degree, grade average & major
Detail your involvement in extra curricular activities and include personal experiences
Use bullet points, write in clear, concise terms using active words
Keep it 1 page
Detail any work experience: volunteer, internships, independent contractor, part-time, full-time

Yours looks great. Just avoid long sentences. You want to go for short, succinct yet clear points. Be more specific with your objective.
