Hi I will be moving to germany soon. I will be moving with my husband and child . My husband will be working out of ruesselsheim.Want some advise about:

a)Which is a good locality near ruesselsheim where I can put my son in an english speaking school? I want the nearest town city/town outside ruesselsheim from where my husband can commute to ruesselsheim.
b)IS 1800 Euro after tax + accommodation ok to survive? Medical will also be paid.
c) If i am coming as on dependent visa- how do I get a work permit?Is work permit mandatory for dependents?
d) What is the average cost of commute per month if one has to take public transport?
