bamboo flooring is great. I have used it many times. Bamboo is renewable resource and is cheep. It is also naturally water proof and extremely strong.
If what you bought is solid bamboo planks you can just install it like hardwood flooring. I suggest renting a pneumatic nailer to get the job done.
Walls first, that way you don't get anything on the new floors. If you look at modern home builders. The painter usually comes in right away and sprays the whole house. Once it is painted the tilers, cabinet installers, and finishers do their thing.
