Returning to RS...

I realize there's a billion of these posts, but many of them didn't cover the stuff I'm interested in.

I'm thinking about returning to RS, and was wondering about a few things that would influence that decision:

1. Auras- Are they game breaking? If I'm slaying with someone who has one, will I be competitive with their speed?

2. The state of PKing- What's it like now? Has it gotten better, or has it suffered from power creep?

3. Skills- Are there any "AFK" skills (woodcutting, fishing, etc.,) that make remotely decent money?

4. Dungeoneering- Have improvements been made to it? I quit about 2-4 months after it came out, and it wasn't exactly fun, but you had to have a rapier to be competitive/efficient.

5. I've read that bots are basically non-existent now. Is farming dragon bones decent again?

6. I'm going to go ahead and throw my stats at the bottom of the post, given these stats and about 2m cash pile + slayer gear (guthans, whip, fsh, a lot of uni scrolls/pouches and yips), what would you do when coming back?

7. I understand RS has lost many players; is anything that was super crowded before significantly better?

8. I read something about superheating being profitable in f2p right now- Can anyone elaborate on the method by which you profit from this, or point me to a relevant guide?

9. Speaking of f2p, is anything in f2p worthwhile right now? I'll probably be doing f2p for a month before going members again.

Also, if you have any relevant information/advice/things to consider, feel free to share them even if they don't relate to anything I've asked, there are almost certainly things I don't know enough about to even ask about them.
