Have you been to a comp to watch?
alot of what you need is specific to you, but
The list goes on, try doing in the back yard, no going to the house.
I would say hang out at a couple comps first, see what everyone else brings vs. what you need. I could tell you everything i take but it may not suit what YOU do. There used to be a check list here some where that would be a good start for you.
