Armed with a sense of adventure and vision about the story you want to tell, at the most basic, camera + lens is all you need. Unless you know specifically what you want to do/achieve, I wouldn't advise going into additional equipment yet. Until you've done a few pieces (could be practice runs), and know what you need to support your image making.
For me, starting with the equipment approach, I sometimes end up getting too focused on the equipment than the story. E.g. Need to use it to justify buying it and carrying it all the way, so end up using it for the sake of it, not because it serves the shot. Of course, it might work for you. Some ppl get inspired with new gear and use it to push themselves to experiment. You know yourself best.
Just from my own exp, generally with each new equipment added, there's a physical and mental 'burden' to having it, so when ppl ask me, I would recommend starting as lean as possible then slowly explore adding on as and when the need arises. Start simple. Some of my own fav and memorable shots are really the ones captured solely with camera + lens. I have ever lugged around a slider+tripod for an entire day and not used it for a single shot. Was so irritated at myself by the end of the day :bsmilie:
