I would suggest that the primary people to speak to are the people who will be taking your data for making the professional map and looking at what they consider the norm in the industry. With professional printing of drawn maps by far the standard is the Adobe suite but in terms of GIS I would have guessed arcGIS but I am not an expert at all. There is the http://www.cartotalk.com/ website too which is populated by more GIS orientated people than this one. There are a few GIS people here so worth sticking around for a while but I suspect that you would get possibly better answers over there too.
