Is this dialogue translation right?
I'm reading The Subtle Knife and wanted to see if I could translate some of the dialogue into Spanish for fun. Here it is (the English is first, and the Spanish is next to it):
"How's your friend?" "¿Cómo está su amiga?"
"What friend?" Lyra said, alarmed. "¿Qué amiga?" dijo Lyra, alarmada.
"The friend you're staying with." "La casa de la amiga que estás alojada."
"Oh. . .Yes. She's very well, thank you." "Oh. . .Sí. Está muy bien, gracias."
"Ah, how good. What does she do? Is she an archaeologist?" "Ah, qué bueno. ¿Qué hace ella? ¿Es una arqueóloga?"
"Oh. . .she's a phycisist. . .she studies dark matter," Lyra said, it was harder to tell lies to this man than she'd thought. "Oh. . .es una física. . .estudia la materia oscura," dijo Lyra, era más dificil mentirle a este hombre de lo que ella pensaba.
"Dark matter!" he was saying, "how fascinating! I was reading something about that in a magazine this morning." "¡La materia oscura!" estaba él diciendo, "¡qué fascinante! Estuve leyendo algo acerca de eso en una revista esta mañana."
"Yes. She knows a lot about it." "Sí. Ella sabe mucho acerca de eso."
"I see. Well, here we are in Summertown," the old man said, "where would you like to go?" "Ya veo. Pues, aquí estamos en el Pueblo de Verano," dijo el hombre viejo, "Adonde te gustaría ir?"
"Oh, just past these shops, please. I can walk from there," she said, "thank you." "Oh, solo un poco pasando esas tiendas, por favor. Puedo caminar desde allí," dijo ella, "gracias."
How'd I do? Besides a few words (archaeologist, phycisist, to be alarmed) I translated this all from my own knowledge. Please correct whatever's wrong, or if nothing's wrong, please reply anyway, you can say whatever you want. ¡Le doy gracias por su ayuda!

Your translation is very good. These sentences just need a few modifications:
"The friend you're staying with." "La amiga con la que te estás alojando."
"Oh. . .she's a phycisist. . .she studies dark matter," Lyra said, it was harder to tell lies to this man than she'd thought. "Oh. . .es una física. . .estudia la materia oscura," dijo Lyra, era más dificil mentirle a este hombre de lo que ella pensaba.
"Dark matter!" he was saying, "how fascinating! I was reading something about that in a magazine this morning." "¡La materia oscura!" estaba él diciendo, "¡qué fascinante! Yo estuve leyendo algo acerca de eso en una revista esta mañana."
"Yes. She knows a lot about it." "Sí. Ella sabe mucho acerca de eso."
"I see. Well, here we are in Summertown," the old man said, "where would you like to go?" "Ya veo. Pues, aquí estamos en el Pueblo de Verano," dijo el hombre viejo, "Adonde te gustaría ir?"
"Oh, just past these shops, please. I can walk from there," she said, "thank you." "Oh, solo un poco pasando esas tiendas, por favor. Puedo caminar desde allí," dijo ella, "gracias."
