1) I'd reccomend taking a look Appendix D of the Policy Documents found
here.
Appendix D: WoW Minis Policies:D-19 Tracking Damage on Characters
For competitive tournaments, players are required to use pen and paper to track damage and clocks of each of their and opponents’ characters.
2) And Appendix P found
here. Which penalty is assigned, and the the actions taken, are dependent on what the judge called determines the infraction to be. There isn't nearly enough information there to be able to provide you with a definitive answer on what the appropriate penalty would be.
3) Pretty much whatever the judge feels like. There is no set time limit for slow play, it is at the judge's discretion.
4) I don't believe the policy document specifies this. I would recommend finding the head judge before the tournament and asking them. During a tournament, whatever the head judge says goes.
5) Again, there is no standard specified way of handling this. Some options include putting each figure on a different base and sticking the character cards in color coded sleeves, or putting a small colored mark or sticker on the base of each figure and on their corresponding card.
Edit: Oh, and if you're going to type up your post in Word, I'd recommend pasting it into something like Notepad first and then copying and pasting from there to get rid of all that Normal 0 false false etc. stuff. ;)
