First try to test it with default squid.conf and only adding to the 
localnet the local networks address space\subnet on the current proxy.

SMP can work without any relation to the CARP example.
It is limited to rock cache_dir and ram cache.
I would start with a RAM cache only and a number of workers.
The number of workers you will be required to use depends on your 
network load.
You can try with 2 workers and use the squid cache manager interface to 
see if you have high requests per second rate per worker.
If you need some hints on that I will try to find the exact values in 
the cache manager interface.

Appreciated, I am trying my best with my limited resources.
