I DVR'd the funeral on C-SPAN (I'm sure you can stream it online from them as well).
1. Inside the basilica, the pall replaced the flag over the casket.
2. Father Scalia (the celebrant and preacher), at the beginning of his funeral homily, thanked Cardinal Wuerl (archbishop of Washington) and the bishop of Arlington (VA) for allowing this parish funeral to be held at the cathedral basilica, to accommodate the large crowd. I haven't researched further, but it certainly sounds like Father Scalia was parish pastor to his father--in the Catholic context of multiple priests to a parish. The cardinal was part of the procession, along with Father Scalia and the deacon/subdeacon of the mass and the usual acolytes etc. I was wondering if they might use the extraordinary, but it was the ordinary form of the mass. White paraments as a result. The EF traditionalists have an attachment to black for funeral masses.
3. After these introductory pleasantries, Father Scalia said they were all here because of one man...Jesus of Nazareth. Of course his rhetorical gimmick was to lead you to believe he was talking about his father (a man loved by some, reviled by others, etc). I haven't watched the whole thing yet, but it didn't sound like a eulogy for his father. It was a Christian proclamation of the sure and certain hope of the resurrection to eternal life. I'm thinking that Father Scalia realized the unique opportunity presented him to proclaim the Gospel to a wide audience. Personally, I don't know that I could have done it myself. I know I had no interest in giving a eulogy at my father's funeral--I left that to others.
