In my final project, I'm trying to use two 30 NeoPixel strips, one data pin to #0 and the other to #1. Would it be possible to wire the grounds of both strips to each other, then to the Trinket ground pin? Or do I have to do some wire splicing or something?
Similar question for the 5V lines as well, since when I prototyped with the Arduino Uno I powered the strips externally (barrel power jack to a portable charger) and omitted connecting the 5V lines to the Uno and it worked well. Do I even have to connect the 5V lines to the Trinket in this case?

You do not need a 5v connection between the Trinket and the strips if they are separately powered.Similar question for the 5V lines as well, since when I prototyped with the Arduino Uno I powered the strips externally (barrel power jack to a portable charger) and omitted connecting the 5V lines to the Uno and it worked well.
