1.) There are filler episodes and filler chapters, nobody just includes them because they aren't important or they are part of a story arc already. For light novels, only the sidestories are considered "filler" in a sense that they cannot be included in main storyline (because as stated they are sidestories), like SS2, which happens over a course of the year and works mostly with a theme on Gemstones. Sidestories that are direct sequels or are part of the main storyline, like SS1 (which continues on with the events that occured in volume 13) are story arcs as well, and hopefully, the sidestory for Liberal Arts City will be adapted into the next Railgun season allowing it to become "promoted" as an arc.

2.) It is not addressed. Only Therestina is a known esper that has become an adult.
