non documented pinoy going back home

[JE57 239]

As for your concern regarding entering the country in NAIA - My wife and I travel back and forth to the Philippines frequently.  Since your new president we both feel that there is a whole different feel to the place.  Everything seems ever so slightly more professional and up to International standards.  Sure you "may" be called into secondary at the immigration counters to ask details of why you were in the USA so long without a valid visa to do so but even if that is to happen then you have not violated any Philippine laws and you'd be let thru.  Also being that you've been in the USA as long as you have if you show up with lots and lots of luggage you may be subjected to customs inspection and be required to pay import duty on any items you are bringing to the Philippines that you acquired in the USA.  However,  even this seems unlikely as on our recent flights into NAIA terminal 3 we've arrived at the same time as flights from the USA and we've not seen anybody being asked to have their bags inspected whereas before it was common that maybe 1 in 4 would be inspected.  Since the new administration we've not had any inspection of our bags whereas before about 25% of the time they wanted us to open our bags.   So in summary NAIA seems much better now and I think you can relax a bit about that.    

As for the other items on your list.  As others have said... you can exit the USA with a valid passport.  You will not pass thru immigration to exit the USA like you would in the Philippines..  When you get your boarding pass the airline may verify your passport and the airline may also verify it again at the gate but no immigration on exit.
