I wouldn't personally recommend a home birth... while I had two natural births, one of them had the cord wrapped around his neck...it was the quick thinking quick handed doctor that kept him from being "hung" from that last big push!
I heartedly recommend Lamaze lessons...and hypnotherapy to deal with the pain issues. Lamaze will teach you the rhythms and breathing and calming necessary... and the hypnotherapy can help you not feel the pains, but only "pressure" as the contractions become what may be normally unbearable without drugs.
If you must have an epi, doing at the last you can hold out...that way there's a possibility that none of the drug will enter the baby.
