Yes, it's built in.



You don't need to set it up.  AM will set the command line correctly.  You just need to define a pool, a miner, and then tell the miner to use EWBF on that pool.  AM does all the work from there.



Not especially, no.  I run it on a simple virtual machine on one of my low-end vmware nodes.  The node has a low-end Athlon 5350 CPU.  I gave the VM two cores and 4GB of RAM.  It runs fine... runs an average of 15% CPU on that piddly VM with the resources given to it.
