-> (9) - "

• Taunt the Prisoner (3): a woman prisoner is in the cell on the north-east section of the middle tier. Converse with her and taunt her (choose the evil dialogue option: quiet rat, blood tithe, your husband is dead, we should dispose of her). You will gain four status points for every successful taunt."
  

-> The Prisoner is Maria Gadderan and she is actually in the north-west cell;

 

-> (13) - "The tree will break free of its ropes, allowing you to chop some wood from it."

 

-> You can chop wood from it, however the tree stands attached to the ropes and wires and such;

 

-> It is shown a few times on the guide that you need to recharge the medallion, take care to do not run out its charges and such, but it is not shown how to recharge it;

 

-> Now, a tip (:

If you teleport to north of Port Phasmatys using Ectophial and then teleport to Darkmeyer by the medallion, appears on your chat that the "due the nature of your teleport, the medallion does not use a charge". It will not use a charge if you teleport from Morytania. :)

You've misread the sentence. It says "north-east section" not "north-east cell". The guide is only describing where to locate Maria in general, not which cell she's located in.

The medallion has 10 charges total, and teleporting to Burgh de Rott places you directly outside the cave where you can effortlessly and freely recharge the medallion. In the rare event that you forget to recharge it and use up the 10th charge, if you've obtained the proper Temple Trekking reward, you can teleport to Burgh de Rott using a Games Necklace, or reach Burgh de Rott by the regular alternatives. By additionally using the Ectophial, you're spending the time to teleport twice and refill the Ectophial, which is roughly the same as teleporting directly and recharging the medallion, but you're using up an inventory space for the Ectophial too (a one-click teleport is handy, but is unnecessary for this quest).

Now you said how to recharge it, yeah, it doesn't makes sense teleport twice :P
