I personally dont care whether our customs were based out of pagan festivals or created for the celebration by early christians, the simple fact of the matter is that this time is a celebration of our Saviour.
That being said its not quite as simple as you state, to ignore the pagan customs that assimilated themselves through necessity into early christian history is to ignore history itself. Estre,Oester,Ostra are all variations of a Fertility Goddesses NAME not a month, the months name was usually followed by a tag such as Easter-monadh.
As far as your contention that Mary Magdalene carrying eggs, that is entirely extra-biblical and in fact a (fairly)modern MYTH. What is known is that pagans of the period had celebrated the spring equinox through the fertility goddess of there particular region by using eggs (and rabbits) as a symbol of that celebration well before Christianity existed.
Now all of this being said does it matter? Do we celebrate a rabbit over our Saviour? Is egg hunting more precious than remembrance? No of course not but to go against history to make origins of festivities change to fit a religion is doing yourself a disservice.
Anyways thats my 2 cents.

Well, we in the Christian East have good recollection of lots of 'extra Biblical' facts: the Scriptures aren't an axiom system from which everything which is true about Christ and God are derived, but the primary written part of Holy Tradition.
St. Lazarus, whose resurrection by Christ's command the Christian East celebrated yesterday, went on to be Bishop of Cyprus, his tomb is inscribed (in Greek) "Lazarus of the four days, friend of Christ", and his bones were moved to Constantinple by the Emperor Leo the Wise; The Samaritan woman at the well was named Photini, and died as a Christian martyr; the child whom Christ called to Himself, when He told His disciples to 'become as a little child', was named Ignatius, and grew up to be the third Bishop of Antioch, and to die as a martyr, fed to lions by the Romans; St. James, who presided over the Apostolic Council, recorded in Acts, was the first Bishop of Jerusalem (hence his presidency), and is titled "Brother of the Lord", because along among St. Joseph's children by his first wife, he would acknowledge Jesus as his brother, and shared both the exile in Egypt and his inheritance from his father with Christ. These are 'extra Biblical', too, but nonetheless true.
Like I said, "Those who cannot remember the past are condemned to make it up."
I understand where protestants are coming from, but your spiritual forebearers threw out a good deal that was true and holy when they decided to get rid of papal corruptions by tossing out all of Christian tradition except for a shortened version of the Scriptures.
