Enjoy your travels I don't think I can add anything other then best wishes really. I've been to Manila a few times now and have always enjoyed it there but I rarely speak out in public for avoiding unwanted attention and I always let my Mahal do the chit chat!
I've carried a lot in my luggage and hand luggage never had a problem and my first trip I had xbox 360, two laptops two iPads pretty expensive camera and had no issues.

Have a good trip I'm heading over around 20th august and will be in Manila for a few days.
