I'm planning on building floor-to-ceiling bookshelves completely

I agree with the majority here who suggest taking the carpet up and
cutting it back to the bookcase one they are installed.
If you go to a wood floor later you can always cover any space left
(between the new floor and the bookcase) with a base board or if you
have a toe space you could use base shoe.
BTW, if you are going to build these on the floor and stand them up,
be sure they are short enough to turn up in the room.
