Lvl 150 Chaos is actually easy if you compare it to the Lvl 100 one in IC, because he doesn't tend to spam HP attacks, and all of his BRV attacks (except for the column of fire) are easily blocked. It will just take longer to beat him.
Yeah, i'm stuck on 99% PP shop as well, I really don't know what am I missing too.
I haven't used Jecht much, but he does look like a brute, especially for his innate ability to break through defenses with his charged BRV attacks.
