There are different methods to calculate the area per lipid, check the 
literature. The easiest way is to divide the area of the box by the number of 
lipids.
To get the order parameters you need to make an index file that contains all 
the atoms you want to include in the order parameter calculation. Use 
make_ndx. After that, try g_order. You may also want to read the manual.
