Umm, yes.
Until we send another to go fetch the crew and/or repair the SSTO. Which, I believe, might have been possible here had NASA thought of it.
No; the next shuttle flight was not scheduled until Mar 1, far longer than the life support endurance of the Columbia.
Until they ablate away or fall off.
Has that ever actually happened to a spacecraft in flight? Since an ablative heat shield is a one-use item for a specific mission profile, it's almost trivial to make sure that it's good enough to survive that mission. Also, ablative heat shields tend to be one-piece units, which means that they are not particularly prone to falling off.
