Regarding most of Westlake/ the Eanes School District, it is not very "walkable", but if you want to drive your car to one of the many "Strip Malls", mainly on Bee Caves Rd., you can walk around each mall. Some have very cute (but pricey) boutiques. Again, price would dictate where in the Eanes district you would look. The homes range from 350K to 6 or 8 million.
If you want to look a little on your own, go to: http://www.austinhomesearch.com
and type in a residential search, then choose "West/Westlake" to see the types of homes. For homes near The Barton Creek Mall (Large mall with Macy's, Nordstroms, JCPenneys, and lots of small shops), type 78745 into your search.
I would agree that zip code 78704 has the most "Walkable" shops nearby, but if you want to be accepted into the Eanes district, you would have to get onto the list to get an accepted transfer for your child.
Most of the schools within 78704 are not the top knotch ones. However, the re-sale value of homes in Travis Hts. is very high. This neighborhood is very artsy, eclectic, and includes "Keep Austin Weird" types of homes!
