Best options for Hong Kong to São Paulo 2016

[ffnovice]

Im seeking advice as to what is my best option for travel from Hong Kong to São Paulo in February 2016.

I am looking for a return ticket from HKG - GRU on Feb 3rd and returning 15th (rough dates), and preferably flying Oneworld.
I wanted to know whether it would be best to purchase my tickets now, or wait a little while, not too sure whether prices will fluctuate at all in the coming months.
I have QFF points and wondering whether I have any options to redeem them ex HKG.

Thank you in advanced!

Forgoing Oneworld I think you can fly SQ metal HKG-SIN-BCN-GRU.
