For the second thing about Railgun-chan...
The reason is... because that wasn't their first meeting. They had already known each other (not name though) for around a month.
Their first meeting went something like this...
1. Touma finds her trapped by delinquents (she must have a talent for getting trapped by delinquents...).
2. He tries to budge in.
3. She snaps at him for trying to get into someone else's fight (completely unreasonable reason)
4. She shocks him... tries to.
5. Doesn't work.
6. Surprised, she tries something else...
and we have the current situation of her trying to kill defeat him everytime they meet.

Thanks for that further clarification. Somehow, that seems more amusing than how it was depicted in the Index manga, perhaps even the Railgun manga. I can almost imagine Mikoto trying various things with the "That-didn't-work-either?" look on her face . In there(Index manga), it just was completely out of left field, so I hope the anime depicts it moreso like the novel or at least like the Railgun manga as I'm sure it wouldn't make sense the way the Index manga shows it.
