Doesn't matter which fixture. The one that has the leak creates the problem.

A fixture carrier is a device that keeps the toilet off the floor and used on basins especially commercial and handicapped applications. These carriers support the weight of the fixture and the weight of people who use a wall hung basin as a support. SEE JR SMITH as they make out standing carriers. http://www.jrsmith.com/
Hard flooring, and yes, it is much more likely to transmit sound.
Yes more than likely. I believe it does have a plumbing and hardware department.
There are companies that solely do residential plumbing. They are most likely independent companies that are easy to locate. Residential and business plumbing greatly differ, so there are companies that are not prepared to try their hand at business plumbing.
Wallmart does in fact sell hardware flooring online available to customers. In fact, it is more likely to find hardware flooring at walmart rather than at target.
Flooding.
I have the very same problem with my Crane Plumbing toilet. Not every thing gets flushed down and can take 1 to 5 flushes to empty. Crane is the cheap brand that builders use. The one in your home is most likely (like mine) the $80 builders line. I found this out when I paid a visit to Home Depot. The resident toilet expert there told me all about toilets. It could also be a blockage or build up in the plumbing.
Bamboo hardwood flooring is actually a lot better in many aspects compared to other hardwood flooring. Bamboo is very versatile and is more likely to hold up when compared to other hardwood flooring.
A flooring nailer is similar in appearance to a nailgun, but it is purposed exclusively for laying floors. This is a better option because it is less likely to damage your floor.
They are only obliged to put in a specific kind of flooring if it is in your contract with them. Many places will allow you to put in special, removable flooring but you will most likely have to make arrangements with another company to rent the flooring and install/remove it as part of your rental agreement.
You likely wired it wrong. Not sure what you mean by "fizzle out".
