Sounds like the same point as me. I am buying everything you are, but I also want to buy some skin raw and paint everything myself.
I went ahead and made a duct tape dummy of my waist up (damn my wife and her camera when I was all taped up!). I bought some foam sheets at walmart, some basic art stuff, ordered some Sintra to eventually make my armor out of, and started working on what I wanted for my armor. That alone has been a much slower and much more gratifying experience. In one week, all I have done is mock up one side of shoulder armor, and I am still tweaking it. So many things to do. Picking one thing to work on has really helped me feel less overwhelmed. Now in the evening, I sneak into my little room in the garage, crank up my iTunes, and just draw, cut, tape, mock, rinse, repeat. I know that my taste will probably change as I work on my stuff so I am trying not to jump right into the expensive items I am going to source out.
Hope this helps somehow.
