--Espero no haberle sacado de la cama.
--Que va.Apenas habia empezado a decir el Jesusito de mi vida.
Here, in Spain, if someone is Catholic before going to bed he/she recites the "Jesusito de mi vida" or the "Ave María". I mean the "Jesusito de mi vida" it's only a prayer. And in this sentence it means that he or she doesn't matter if someone has interrupted her or him because he/she has just gone to bed.
Está un poco tocada del ala.
It means, simply, to be crazy.
Con un hilo de voz
As Hairo has said it's because the size. As the thread is very very fine it means that her or his voice was very very soft.
I hope it's useful. :)
