Precious Metals

So I only escrap when i find a computer, tv, etc... Nothing in bulk. I enjoy tearing these critters apart, but do not forsee a large quantity coming my way and do not want to start getting into paying for things to take apart. This is from my own ignorance, I understand, but I have no basis on what to pay for what, as I have never cashed in on boards or anything yet. My questions are;
1) do I keep stockpiling low grade boards, or just give them to someone who deals in bulk?
2) I don't know what to do with with the green boards I have, since I only have 5 pounds if I'm lucky. Without buying junk computers in bulk, is this part of the business worth it for me, I understand the YMMV concept to an extent, but until I get a pile worth selling, won't know.
3) Picked up two household breaker panels last night. Brasscatcher said there is silver contacts in them, but I would say only a total of 40 breakers. I don't come across these often, so is it in my best interest to try and harvest the silver?
4) Does anyone want to buy 35-40 used circuit breakers? I have no clue if it would be worth paying shipping costs?
Anyway, maybe I will leave the electronics to the big guys, I only started picking up CRT's because I was noticing cut cords and a tv still sitting there on the curb. Or I guess I should say tvs with cut cords.
-I'm not even sure if I can distinguish the difference between gold and brass, silver from aluminum... therefore no OMG IT'S GOLD!!! bucket.
and one last question:
-If there was a stripped CRT on the side of the road for weeks, with all the goodies gone, would you pick it up and appropriately dispose of it out of good faith in humanity?
and another;
-WILL SOMEONE PLEASE TELL ME? WHERE DO BABIES COME FROM???!!!???
