4 questions from a beginner

Hi, I've become obsessed with pinhole photography and
I've got a bunch of questions that I need help with.
I'm sorry for so many questions at the same time.

Question 1

I've turned an old autographic camera into a pinhole
camera. I've got a .013 needle hole and 1" from
the hole to the film. I've got it loaded with 400
speed b&w film. So my question is where should I
start? In my paper as film pinhole cameras I start at
about a minute in sunlight. How long should I try for
an exposure on a sunny day? Am I right in gauging the
f stop at f/77? I've got a light meter, should I use
it and should I make any adjustment for using a
pinhole?

Question 2

I've made a 250 sheet photo paper box pinhole camera
with a .013 hole. I'm not getting nearly as much
light around the edges as in the middle. I thought it
might be the pinhole, so I made another with the same
problem. Is lack of light on the edges normal?

Question 3

A friend gave me a box of ilford ilfobrom 4.1P paper.
It works fine except that the edges are curled up.
Any way to fix that? Would putting it in a hot press
thing help? Also, does anybody know what the
qualities of this paper are in relation to other
papers?

Question 4

I'm sure this is a repeat question, but do I take
developing chemicals to the haz waste pickup place or
is Seattle's waste division capable of handling the
chemicals down the sink?

Thanks,

Bre Pettis
