I think I have already posted similar to all the things below that I agree on, so I won't go over them again.

Little girl... the mercury idea
I think Sherlock knew that Richard Brook was Moriarty
If the assassin on John was outside the hospital - how did Moriarty know that John would go there? That's something I can't work out. Sherlock chose the location of their showdown but Jim got there very quickly, which meant he must already have been in the area - did Jim know they would meet on the roof too? I have no idea!
Jim didn't really get there quickly. Remember Sherlock texted him and then the next part is john waking up to take the call about Mrs H so there was some time between that where John went to sleep on the desk etc.
1. Ask for help - he asked Molly, and most people believe Mycroft had a hand in it, which must have been pretty hard for Sherlock considering their relationship
Sherlock has asked for help in the past eg graffitti artist; alsoMycroft & Sherlock ARE close remember the scene in the morgue after identifying Irene's body and a few others as well. They portray their relationship as a testy one to others, but alone they are fine.
2. Allow himself to be made a hero
3. Get into a taxi without John - normally he likes John to talk to when he's thinking
Sherlock is at his most vulnerable when not with John. He also needed to lure Moriarty into his next step. Best he was alone to do that.
4. Showing emotion/tears whilst on phone to John
He cried at will in the great game when talking to the dead man's wife. He was acting, he had to convince John this was real
5. Calling instead of texting
He's called people several times eg Mycroft in HOUND when he needed to get back into the lab. He said he prefers to text earlier in the series, those times were to criminals, not associates/friends.
6. Dropping his phone before he jumped - why not just put it back in his pocket?
Why be neat and tidy? He was going to die, you don't need a Blackberry after that!
I've always been a bit suspicious about the Mycroft telling Moriarty secrets about Sherlock storyline - Moriarty never actually used any information like that, ....... unless there was some other info in the article that John read but that the audience weren't privy too.
Agreed on the information thing. As for the article not showing what John read etc, we know that Moffat said all the information we need was seen in this episode. So we don't need to speculate on what we don't see, it wasn't of any relevance.
I think the computer code was real but not as dramatic as Moriarty initially made it out to be
Sherlock has such a rubbish relationship with his brother though, it's hard to imagine them like talking on the phone and planning to dupe Moriarty together so... I dunno. Lost again, lol.
Again, don't be fooled by the 'show' of a deep set resentment or anything. These 2 guys are involved with each other in some dangerous business; if either brother didn't trust the other implicitly it wouldn't happen that way. No honestly, do not be fooled by the sibling rivalry, they are brothers & they are 'close' on a different level. Just because it's not an emotional level, doesn't make it any less a relationship built on understanding and trust.
