I agree with all of the other advice, you really will need to ensure you have more money. If your tight you should have a credit card with enough limit for emergencies.
Ensure that you have a comprehensive travel insurance policy which covers the Philippines and all emergency medical treatment.
Take a photocopy of your passport, insurance and travel details and pass this on to someone at home and take a copy with you seperate in your baggage.

I don't think the Philippines is a Yellow Fever area, so thats not necessary. As for Malaria, in North Luzon it is unlikely you'll be affected but do check. Also do some research about the tablets you'll take if you do take anti-malaria ones. I have my own personal opinions on this which may not be the view of everyone.

As for cabin baggage allowance, it depends which airline. But if its with the major carriers then normally you'll be allowed a cabin bag upto around 10 or 15kg PLUS a laptop. If you are planning on using any internal flights in the Philippines, some of them have serious baggage restrictions on the ATR and Dash 8 Turboprop Aircraft. But I'm guessing you'll probably be flying into Manila and then catching a bus up North.
Remember that you are not allowed liquids or sharps in your hand baggage. You can carry a small clear pouch, and would recommend you put some small toothpaste, a mini deodorant (you can get these in boots and tesco) etc. Always put a spare set of clothes in your hand baggage, and anything which you would really need when you get to the Philippines. Most of the times your bags will arrive untampered, but occasionally bags get delayed, go astray or have items missing.
Also, you'll find that people in the Philippines are very friendly and helpful, but don't let this blind you from the con artists, crims and scammers that you'll find everywhere in the world.
