I hope responding to my own message isn't a big no-no when there is something of substance (I think) to post:
After rooting and installing superuser and accessing the SCH-i810 using the "Root Browser" posted here at XDA (thank you), I determined that I could cut the two files:
paste them both in
And now the SCH-i810 boots with no animation.
The momentary Samsung 7.7 splash remains but, otherwise nothing until the home screen appears in about 18 seconds.
Maybe this info helps someone. The Verizon boot animation was just too much color flashing and movement. The animation might be great for the store but for everyday use -- ugh.
