3 questions about chapter 1

Hi guys.
I'm kinda new here (please forgive me for any grammatical mistakes I might have, English isn't my first language)
I have 3 questions regarding chapter 1.
I think I saw somewhere (not on this forum, I've searched) a discussion about Cocka cocka and his development. If I'm not mistaken, it said that around level 30 he becomes an adult and that for some reason it is recommended that he should become an adult before moving on to chapter 2.
Why is it and is it really worth doing it?
My second question is related to the first. If it is recommended to do so, can you recommend about good spots to level up, since the best one for my level (Randon and Sarah are both level 20 and Cocka cocka is level 19) is the norther part of the Metrolian ruins, fighting the wandering Mist wraiths. Leveling up like this is quite frustrating.. If you have better places, please let me know.
My third and last question is about money.
I've read that I should get the blade that is being sold in the nomad market (the deal with the weapon merchant). It costs 12k, and in addition I want to buy the rare items from the wandering merchant that were mentioned in the walkthrough. Everything should cost me about 22k+. That's not alot of money but there aren't too many places to get good amounts of money in the first chapter.
I've already sold the Pirate's treasure for 1058 gold each, and I'm trying to get the money from the eastern part of the Metrolian ruins (where the vampires are).
Do you have any advices regarding where I should get the money?
Thank you very much in advance
