Correct and acceptable Irish FBR application documents

Hello friends!

I am in the process of applying for Irish citizenship by descent through my grandmother who was born in Kinvara, County Galway on September 29, 1881. I am registering on the FBR website and I am confused as to what documentation is acceptable and what documents are unacceptable. I want to be sure that my application is not delayed from submitting improper documentation! Can someone knowledgable about the correct to do this advise me?

So far, I have applied and gotten an application number, and have had 4 passport photos taken with true copy certification (signed, stamped, dated, etc) by a local United Parcel Swevice (UPS) manager and notary, I have documentation COPIES of the originals only from Ancestry.com, but NO true copies that are certified/notarized, except the one of my biological birth certificate - because I was adopted later at age 12..

I do know that I have to get my US state of Tennessee driver's license copied at UPS and made into a true certified & notarized document..But what about the simple photocopies of my grandmother's Irish Civil Birth Certificate, etc,, or the photocopy of my biological father's 1913 birth certificate copy (dated 1961)with the form having handwritten dates and names? My father was born in Chelsea, MA in 1913 - the same year that my Irish grandmother married my grandfather. The MA vital records website states that the earliest MA vital records are for 1926. Earlier such records are in the archives division records and are public records. In 1913 Boston (where they married) marriages were recorded in a marriage registry book for 1913. 

At the Irish website www.ie it states:

"Documents related to the applicant and Irish citizen parent/grandparent (unless stated,originals must be submitted)."

I researched and have original copies from www.civilrecords.irishgenealogy.ie. Are these downloaded photocopies acceptable documents for applying for FBR descent citizenship?

Thank you SO MUCH for any assistance in this very important question!
