The information you seem to be after is all in chapter 5 and/or 
http://wiki.gromacs.org/index.php/Parameterization. If you need to 
present pdb2gmx with a structure including a residue with an unnatural 
heavy atom then you will need to make a new .rtp file entry. However the 
above is not a topic for newcomers. It is highly recommended that you 
get some MD and/or GROMACS experience with some other system first - at 
the very least do all the tutorial material you can find.
