*Your circled item is the cruise control.
*The tank below it is the sub-zero start coolant tank. It is useless and Mazda told their dealers to remove it whenever a car came in for service.
*The item to the left looks to be a pissed-off girlfriend.
Sometimes removing the rats nest will introduce running issues and makes diagnosing issues more complicated at times. Its a very simple system that functions well and removing gains zero power gains. With the stock carburetor and emissions equipment, there's really no need to remove it. The only benefit is that it makes it easier to remove the carburetor. The carb can be removed easy enough with the rats nest in place.
At the end of the day its your car and you do what makes you happy. I've been down that road and have tried different things and were never happy with the results on a stock carburetor with the emissions rack removed. Just trying to save you some headache.
With the removal of the rats nest, it also requires removal of the air pump and ACV block off. This in turn means you can't run a cat in the exhaust.
my air pump went out some time ago and my continued driving led to a clogged catalytic converter. I knew had to remove the acv so I went a few steps further.

what’s your opinion on stripping the carb? I’m going to be rebuilding it and I was considering removing unnecessary parts.
The parts only become unnecessary if you remove the other emissions components. Everything on the carb is for idle control, deceleration control, and secondary operation. Some people like making the secondaries mechanically controlled instead of vacuum controlled. I've tried a bunch of different carb configurations over the years and the stock setup provides the smoothest throttle response and idle. A stripped carb with mechanical secondaries can be a handful at first but once its right, its not bad either. I just hate headaches and the older I get, I'd rather not mess with something modified on a car I'm going to take out and cruise. Something for the track is much different, as driveability is out the window. It can have a higher than normal idle and who cares about gas mileage. I just don't mix the two anymore. Its either a nice stock or mostly stock driver or its for the track and its modified.
