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.
