1. Preparing my structures I have encauntered that aromatic amino acids
in ff43a1 FF have "C" carbon type instead of "CR1" in aromatic rings.

Are amino acids treated somehow different in GROMACS than other
compounds ?

2. gromos ff have "gromos type" column in *.rtp files with many
different codes (e.g. ga_17, gi_1, etc.). What does it mean ??? I did
not found any describtion in GROMACS manual.
