Sounds like you got it well sorted Jonny...especially the packing and loading element
Regarding customs, tax and fees etc I just remembered that Executive Order No. 206 (ammendment to Section 105 of the Tariff and Customs Code of the Philippines) allows some special duty and tax free privileges for Returning Residents, Overseas Filipino Worker (OFW) and Former Filipino's.
There are conditions and restrictions (as always) but maybe helpful if you haven't already been made aware of it.
Here's the Bureau of Customs webpage with some details and numbers etc.
