yes goto google and search for "dvdinfo" no quotes and find and download dvdinfopro its shareware but the trial period should suffice to gain the firmware information
not sure if you mean do you need to install the firmware or not or the program to determine the firmware you have already !?
lets start with the program to determine yes it needs installing
firmware yes or no to install it .. its personal choice down to you
do you really need it !? yes or no !?
most people install the firmware to either a) have region free with their dvdburner/dvdrom or b) to gain extra functionality/better compatibility with medias
the choice like i said is really down to you
