I love this board! I wish I we had it when I went back to work with my DS in 2005 and was juggling the pumping schedule. Now I feel like a pro with my 8 month old DS. However, I have to say... It's hard! But so worth it! All of you ladies deserve a huge pat on the back for your commitment. So many others don't even try. I went back to work when my son was 12 wks old

and made it to 12 months without a single ounce of formula. (that got hard when we needed to use my milk for cereal and other food mixtures) This time around I realized that some formula for mixing w/ food is just fine and reduces my production anxiety. I too am one of those lighter producers and struggled a lot with DS. My tips are:
1. If you have a newborn, start pumping and freezing from the very get go. Keep that production high even if that means some milk expires and you have to throw it away. (I've got a 2 month supply in my freezer at this point so I don't stress like I did the first go around) If you didn't do this..don't worry, you'll still be ok. This is just insurance.
2. I've always used a small manual pump for the morning feed. LO feeds on one side (football position on a boppy works best) while I pump off the other side. Then when LO is done I would pump off any extra from that breasts. If you start that from the beginning you'll be amazed how much you can pump. Warning..I have to say that this added an extra 30 minutes to my morning, but was soooo worth it. (also great bonding time)
3. With DS I pumped every 3 hours which was really frustrating but somehow made it through. With DD, I now pump every 4 hours which makes my day a little more sane.
4. Any time I've needed to increase supply, I've focused on drinking tons of water and using my manual pump after feeding LO. (regardless of how little came out)
Its really important to keep up those consistent pumping sessions especially as LO gets older. In my case, both of mine have started to wean themselves. He/she is just too busy and needs to see what's going on. So I find that around 7/8 months my production really starts to drop. Therefore, I have to stay consistent. (even those special times when I get a date night with DH. I still bring the pump in the car if too much time elapses)
I hope this is helpful to anyone starting out. It's a lot of work, but once you figure out your own system (use of mom's rooms, washing pump at work, scheduling meetings, etc.) it starts to fall into place.
Good luck and know you're not alone!
