Most of these are generic Information Technology Risk Assessment documents. If you need a good resource for the HIPAA Security Risk Analysis which includes assessment for Administrative safeguards, Physical safeguards and Technical safeguards, then check this http://www.training-hipaa.net/template_suite/HIPAA_security_risk_assessment_analysis_template_tools.htm 

Normally companies charge anywhere between 10K to 20K for doing this type of assessment. I would recommend that before you start the assessment go through comprehensive training like Certified HIPAA Privacy Security Expert (CHPSE) as it looks like are very much involved in your HIPAA compliance. Comprehensive training will help you understand what you need, why you need etc. After having clear understanding of HIPAA regulation, it is easy to do the risk assessment.

The network vulnerability assessment (Pen testing) is something that you will have to do it on your own.

HIPAA requires employees to be trained based on their job role. Even if you employee is temporary employee. Based on the job role of the person, you will ask them to take necessary training. If you want them to take the basic training, you can ask them to do the Certified HIPAA Privacy Associate (CHPA) training http://hipaatraining.net/hipaa-certification/certified-hipaa-privacy-associate-chpa.htm  which includes HIPAA security overview. If you want them to have comprehensive HIPAA security training then you want them to go through the Certified HIPAA Security Expert (CHSE) http://hipaatraining.net/hipaa-certification/certified-hipaa-Security-Expert-chse.htm 

All consultants or companies providing temp staff are the business associate of covered entity. All BA have to comply with the HIPAA regulation. If you have temporary employee, they are still part of your organization and your organization will be responsible if there is HIPAA violation caused due to their action. The key is that the person has to be trained based on their job role.

If you are covered entity, download this questionnaire of  HIPAA compliance status of the business associates. This helps you to ensure that BA meets the HIPAA standards.  http://www.compliancehome.com/whitepapers/HIPAA/abstract11982.html
