This set of instructions will not use the above FFTW in GROMACS. The configure command is inappropriate. Please see the installation guide for the proper approach.

This is a fairly basic UNIX issue, and has nothing specific to do with GROMACS. You need to have an appreciation of what the UNIX environment is, and how you can "source" a file to adjust that environment. Please look around the web for some UNIX tutorial material - you'll need some experience and knowledge here before you can do anything at all. Once you understand the need to adjust the environment, you can see how "sourcing" GMXRC will solve some of your problems.

That's not really the purpose of pdb2gmx. It tries to generate a topology from a set of coordinates. Perhaps working through some GROMACS tutorial material is a good idea to get the beginnings of an understanding of the workflows work.
A file in specifically .gro format is not necessary at any point - see http://www.gromacs.org/Documentation/File_Formats/Coordinate_File#On_the_need_for_a_.gro_file
