But I just say that so that you know it isn't a gaurantee that you'll hurt you or your baby if you're on your back...even at 34 weeks.

The inferior vena cava is posterior to the abdominal cavity. It's lying on your back late in pregnancy that's the issue, not lying on your stomach. Lying on your stomach is not detrimental, it just gets uncomfortable and unreasonable at some point because of the size of the belly.
RedWifey's totally right that pregnancy isn't an illness. You're a healthy person who should continue to exercise.
It's fine to continue with the lifting program you're doing now and no substitutions would be necessary unless you find the movement uncomfortable. There's no need to reduce the loads you're lifting at this point either. This particular program doesn't ask for 1RM testing, which would contraindicated during pregnancy, but lower reps, as in the 4-8 used in NROL4W, are fine.
This early, dissipating heat in the body is your biggest concern. As blood volume begins to increase, you'll find yourself getting hotter sooner and having a harder time cooling off. The fetus cannot cool itself, but is only cooled by your circulating blood. Keep that in mind during energy system work and don't let yourself get overheated.
Powerlifter Julia Ladewski lifted all through her first pregnancy. She announced in June that she's pregnant again, so there should be more from her on the subject in the upcoming months. She has a newsletter that doesn't come out very often, but you might want to sign up for it. Here's her website:
About Julia - Ultimate Training for Athletic Performance and Physical Enhancement.
Here's a Q&A from her on the subject:
EliteFTS - Superior Products and Knowledge for Lifters, Athletes, Coaches, and Trainers
One of the best pregnancy and lifting articles I've ever read is from Krista Scott-Dixon:
Weight training during pregnancy.
Those will get you started in learning more about lifting during your pregnancy.
