Depends on the shade. Bring some tape to cover it if the inspectors think it's an issue.

2) Does reserve/replacement parts considered part of the 40 pound we can bring with us to the competition? Does spare batteries (in addition to that we sent with the robot) are part of that weight? what about bumpers?

If they're fabricated items, they count. Batteries count if they haven't had their leads removed. Bumpers count. COTS items that aren't modified don't count.

3) Most of the structures in our robot are built with materials we found in our school (polls and stuff) - how should we evaluate their cost?

You can a) ask the school or b) find a commercial price--I believe the actual term is "fair market value".

4) if we sent our robot already and forgot to do the BOM and costs, how are we supposed to evaluate the cost of things...?

Go by memory, print out the list before competition, and write down anything that you missed when you get there.
