Slightly more obvious guide
NB a lot of your questions can be answered very easily: The less you do from this list, the more likely you are to be removed from the pool. It's really that simple.
Incidentally, as some builder's may have noticed I'm quite precious about the wrench/spear combination. If you look at the pool you can see that it is a defining feature of most photographs which lends a nice cohesion to the photographs. Thus precious ;)
I will no longer be responding to caveracers. They've had their day and it is not today.
