To use gauges yes you need the port. To just charge system, no! but there may be a port on the compressor...

Wow, thanks for the quick reply, this is a great website you have. That makes sense, I'll have to check the compressor too but I'm fairly certain there's only the fitting on the hose. My concern is whether or not I "should" have a port in there, say if I later on wanted to have the system flushed or evacuated. I'm just a DIYer so I don't expect to be evacuating in the future on my own but someday I might wise up and bring it to a professional before getting in over my head. If I should have the port is it better to have a hose custom made with a fitting on it or should I be able to find a vendor that sells short lengths with a high side port in it (so I can just connect it between the compressor and hose)?
