Not to be a jerk, but.....
I would suggest a wide angle filter for your lens
That is the last thing I would recommend.
A strong carrying bag for your camera would also be nice to carry into the woods
I never use a bag when carrying a camera into the woods. Your camera man should have the camera in his hands. You never know when something might happen.
Unless you are planning on making a DVD or something, a microphone probably wont be neccessary.
Audio is just as important as video.
I would also HIGHLY reccommend buying an memory card
A memery card is only used if you take pictures with your video camera. Most point and shoots take better pictures.
extra battery and make sure its charged when you go into the field.
This is good advice.
