The San Antonio area is fairly spread out; it takes us about 50min to get from our house on the NW side outside Loop 1604 to my ILs house on the NE side outside the Loop (in Converse). On the up side there is usually a highway you can jump on to get where you are going in a reasonable amount of time. If I have to go somewhere beyond the shopping centers by my house it usually takes at least 20 minutes.
I LOVE New Braunfels (they have a nice children's museum that I had a membership to when we lived on the eastside); I really wanted to live there as it looks most similar to my hometown but the distance to the Lackland area added about 30 minutes to dh's commute in rush hour. If either of you have to commute to work I would test it out during rush hour once you are here. Dh had an old friend PCS here this year and we would have like to have them on our side of town but since he worked at Ft. Sam it was an easier commute from the eastside; the commute to Lackland/Kelly is about the same from either side, and Randolph is on the eastside.
Here is a map (a bit cartoonish) of the Hill Country Area -- New Braunfels is on the lower right.
Here is a map showing the Texas regions and links to specific areas: http://www.tourtexas.com/texasmap_regions.html
Another thing to be aware of are parts of roads, "bridges" (over creek beds), and some highway entrances/exits that tend to flood when it rains heavily--every time the barriers go up you know there is someone that will go around it because they want to pay the $600+ per-person rescue fine 
. There is a neighborhood we looked at behind Rolling Oaks Mall (NE) whose only entrance floods in heavy rain--though it may have been fixed since we first heard of it happening.
I'd also be aware of how close your "essentials" are such as the grocery store; there was one neighborhood we decided against when we were looking as the long drive out of the neighborhood then the trip on the highway just to the grocery was about 20 minutes--not fun with the summer gas prices.
A lot of "specialties," like OT can be found in Stone Oak; not that they don't exist elsewhere--but there seem to me more of them in that area. Dr. McMains off San Pedro (Clock Tower) in Stone Oak sees non-vaxed children; they want you to sign the AAP form but you can cross out the bits you don't like and they don't say "boo." She is an older lady so I don't know how long she'll continue to practice. There is also a DAN Dr. in the area; she's mentioned on some of the older "moving to SA" threads. LoneStar is the frequently recommended OB/GYN practice here. Medical care is big in San Antonio so hopefully you can find what you need here, though Austin or Houston are within a couple of hours if you need to widen your search; Christus Santa Rosa Children's Hospital is in downtown SA, though I don't know anything about their pediatric neurologists.
The "natural foods" chain here is Sun Harvest Farms; I think the nearest Whole Foods is at least an hour away.
There are a few non-religious homeschool groups in SA. I think there is also an API group in the New Braunfels area.
