First off it is GREAT that you have chosen this. It is so much better for you and baby and recovery and family to choose to VBAC vs repeat cs. Way to go on the good choice!
Second, I know it can be hard to find a provider who is as supportive as you need (this is one reason why most VBAC moms choose to home birth). If home birth is an option for you, I would recommend that, as you are guaranteed (unless your MW has an extremely booked practice) to have the same care giver. Also, the prenatals are 1 hr long instead of 10 min, and you don't wait half an hr to see them! Also, most MW understand the emotional and psychological side of VBAC. Your success goes WAY up with a HBAC (home birth after cesarean) than with a hospital birth. If not that, maybe a birthing center? If there is one you feel comfortable in, but you do run into a group practice thing, where you get the MW on call in labor, but they are going to be proVBAC regardless.
Where ever you birth, hire a Doula. It's great you got in contact with your local ICAN. That is such a wonderful start. Our Doula for our HBAC is the local leader for ICAN. Have them recommend a Doula for you who has worked with VBACs. They can give you A LOT of knowledge and information and answer any questions you have. If you do choose to hospital birth you will have that constant support with you no matter what OB you end up having. I think if any mom should not go without a Doula it is a VBAC mom.
The Thinking Woman's Guide to a Better Birth, Silent Knife, Open Season, any Ina May Gaskin books, Birth After Cesarean, The Cesarean Myth, and Pregnancy, Childbirth and the Newborn, are all WONDERFUL books to read. I doubt you will read them all (who knows you may be a super duper speed reader!) but they are great resources. If you didn't do a lot of prep before you last baby, I'd choose Pregnancy, Childbirth and the Newborn as it is an amazing book all around.

A couple things...
1-you can do this. Your body was designed to birth a baby and your baby was designed to be born.
2-learn positions to turn a baby if they are in an unfavorable position (OP).
3-go without any medications as long as possible, especially Pit, as it may cause you to need an epidural, and that may cause more issues combined
4-be mobile, be upright as much as possible when laboring
5-hire a doula
6-eat and drink in labor, even sip soup if you can't keep food down
7-you don't have to have the cEFM, it's not required for VBAC, have a nurse/MW monitor intermittently with hand held device.
8-Hire a doula
9-if you are choosing a hospital birth, labor at home as long as possible
10-hire a doula
There are more tips, but here, I feel are some main things.
ps. Oh, it's not too late to change caregivers, some moms do it at 37 weeks! Never birth where you are not comfortable or with who you are not comfortable with.
