Pasig or Pasay is good. The bus leaves from GMA-Kamuning (a couple metro stops north of Pasig) so you can cab it from where you're staying fairly easy. The bus then stops in Pasay to pick up passengers but it might be crowded by the time it gets there.
You'll arrive in to Batangas pier where you can take the ferry over to PG. Try get it to Sabang but you might have to go into the town proper (Muelle) and then take a water taxi to Sabang (or where ever you're staying).
I can't remember the name of the bus company (I think it's Titan?), but we've talked about it plenty of times here. The price is about P70 one way and leaves regularly (I've never waited more than an hour for it to leave, and usually leaves every 30 mins if there's a lot of people) IIRC so just show up and hop on. I believe the first bus leaves at 5am?
