As far as lightning damage, try to prevent it.
Seriously, the lightning strike will try to find the least resistance
path to ground and you can't predict which path it'll take. As long as
everything is done adequately offering a low resistance path to ground and
dissipate harmlessly, you don't have anything to worry about. Two or three
ground rods at the tower base is a good start.
Insulating the guys will force the strike down the tower while if
uninsulated guys take a hit, the turnbuckles are likely to get welded
Whole books have been written on this topic so it's hard to give you
all the answers in one email. If you're interested in more info, I have a
reprint of the chapter on lightning from my upcoming tower book that covers a
lot of ground (no pun intended). For a free copy, send an SASE with 2 stamps
