The strike rail should NOT be closed otherwise it will look like a shorted 
turn and kill the magnetic fields that make the coil work.

You should connect the strike rail to the base of the secondary which in 
turn is connected to RF ground (and NOT the power cord safety ground) 
usually a stake in the ground, or a water pipe, etc will work for this.

EMI filter is not necessary for the coil to work.  The desirability of it 
depends on what is the surrounding environment (ie, who or what are you 
going to interfer with).  My 1000 watt coil has yet to have a line filter 
and does not interfer with the TV when on its own load panel (breaker box) 
branch.
