1) The SF-424 form provided on the EERE-exchange website is the correct form to submit. Block 21 of the SF-424 document states that by signing the application you certify to the statements in the list of certifications. You do not need to turn in a separate Financial Assistance Certifications and Assurance form.
2) The SF-LLL Disclosure of Lobbying Activities is not a required form if your organization does not participate in any lobbying activities. Your organization must self-determine the applicability of this requirement.
3) You do not need to provide resumes for all employees working on the project, resumes from key personnel, including significant personnel of major participants and consultants will suffice.
