Synagogue

If I'm trying to learn near a Minyan, do I need to stop to answer every B'racha or Kaddish?

Clients of mine want to rent out a building that has served for a family business to a religious group, who will use part of it as a shul. They are concerned that if things do not work out, they will get back control of the building with some of it having the restrictions of a shul, which would restrict their use of it. Is this a problem, and if so what can be done to obviate the problem?

Is there a preference of davening in a Shul as opposed to a house-minyan?

In our shul, the seats have drawers underneath them to store chumashim, siddurim, etc. Thus, we sit over these books. Is that allowed?

People who own sifrei Torah often lend them to a shul. Is there any reason they cannot donate them (which can get them a tax credit)?

Question:Someone in shul told me last Shabbat that I should not wear shorts to shul,he said that Shabbat is different. Why should Shabbat change the halacha?
