Of these, I would place the greatest emphasis on #3.  With respect to 
#2, the real issues are

Termination of the cable shield at each end to the shielding enclosure, 
NOT directly to the circuit board;

and

bonding together of all grounds within the premises by short, fat 
copper.  That includes, but is not limited to, telco, CATV, satellite, 
power, ham antennas, and lightning protection.

I see no relevance to his #1 with respect to RFI. The real issues are 
his #3 and the cable shield issue (The Pin One Problem), both of which 
are well known causes of both ingress and egress with systems of all sorts.
