generally, you pay 1 yr rent UP FRONT (this will depend on landlord...he may be happy with 2 cheques)

Your utilities can vary month-month (eg they will generally be higher in summer)
Some apartments include aircon cost.
Probably a minimum of 400 dhs per month
I cant give you a proper answer on set ups , but Im sure the others will be on soon to help out.
