For a new twist, I am going with a Sierra Club group from Fresno to climb Half Dome this weekend, but we are doing a night climb -- meet at Happy Isles bridge at 9:30 PM Saturday (7/12), on top to watch the Sunday morning sunrise, then back down in the morning. There may be more than 20 hikers.
Coincidentally, there is another group doing it Friday night (7/11), also from Fresno. They are starting out later, I think around 11 PM.
Regarding gloves for the cables: I tried them once. They give you about half the grip compared to no-gloves. I always go without the gloves now -- and have never gotten any blisters or anything.
