Make sure to double check that since T1 is in a separate building from T2 and T3. You don't have that time to waste.

Lounges:
The international area from T2 and T3 are connected but it can be considered a long walk so be aware of that, in case this flight departs from T2.
You can use the Safra lounge at T3 as a *Gold.
T2 international has a Priority Pass lounge, I believe.

Transfer:
I usually stop at GRU so I'm not familiar with transfers but I always hear announcements about everyone needing to collect and re-check bags.
In your situation, I wouldn't risk it with a 2h30 connection. This GRU-PDP flight from Azul operates twice weekly.
