Not sure where you live but this is a brilliant rescue home, they will be able to help you with everything you need to know about owning a Pomeranian. www.pomeraniansforlife.co.uk/
Do plenty of research beforehand, and read up on training (in general) and you should be well on your way http://www.breedia.com/dogs/pomeranian The Culture Clash is a good book, and this guide on Dogsey is a good read too http://www.dogsey.com/about-dogs.htm
I did loads of research before getting my little girl yesterday, google is brilliant it has so much info and even just picking up the phone to speak with the vets is good they dont mind helping you because they know you are finding out before jumping in If your in the UK pets at home is great for advice with the breed/feeding/ideal weight etc good luck
