Will I need to change the rot.file to when I add a new continent?

You can edit the rotation file (to add a rotation sequence for the plate ID of your new continent if it’s not already in the rotation file).

Tutorial 2.4 Constructing a Plate Model From Scratch might be helpful in this regard.

I cannot move my continents

So I have my continents ready, I then make a reconstruction tree, and then select a continent with the f shortcut, move it with p shortcut, but when I click apply, the stats for part 2 are blank, and the continent does not move.
