A good quality hardhat or a helmet is a must.

>Should we be wearing rock climbing helmets for tower work?

Dragging anything along that could catch on a bolt or fitting is 
dangerous.  A small catch could throw off your balance enough to compromise 
your grip or footing.  Also, if your fall is arrested by the positioning 
lanyard, you're facing the high-lateral forces problem again.

One easy method for resting is to attach a spreader to your saddle or hip 
rings, then use a hook to tie off to the tower when you want to 
rest.  Spreaders are not cheap, so a short lanyard may be a better 
option.  If you use a spreader on your saddle rings and suspend yourself to 
work, hook a big carabiner between the hook on your chest ring and the 
spreader', else you might find yourself upside down.

You should not use a fall-arrest lanyard for positioning, even resting, as 
you mention.

Whichever fits your tower members best.  For angle towers, bigger is 
probably better.  There are some side-gate carabiners that open really nice 
and wide, and if you have the spare change, the aluminum ones are excellent.
