My advice would be NOT to pump for the first few weeks. Pumps are just not as good at breast emptying as babies are. You should nurse, nurse, NURSE that baby. No pacis, no fingersucking for the first week at least, just to be sure that the milk is in; I would recommend that you don't do pacis at all, really, because they can reduce supply at any point.
If you need to pump to build up a supply for going back to work or whatever, you should introduce the pump once your supply is well established, usually no earlier than 4 weeks.
To encourage supply, besides nursing baby, you could try eating oatmeal (as a pp said), taking a warm shower before nursing, breast compressions as you mentioned. Try not to stress about it because baby will sense your stress and be a tense (and thus, less effecient) nurser.
And remember: Breastfeeding is completely natural, but natural does not always equal easy. Stick with it and definitely consult an LC if you have questions. Also, I would highly recommend attending LLL meetings now and after your baby is born. Having a good support group can make all the difference in the world!!
I have loved my Boppy with all of my kids; take it to the hospital with you to help you get used to the way you will nurse at home from the very beginning. The hospital may give you extra pillows, but my experince with hospital pillows has been that they are like a pizza box with a pillow case on it; not too helpful!
