I am not planning to use an OS at this point

Sorry, but I still don't know how to download the sample
"httpserver_raw" you guys mentioned several times :( Would you
please show me how?

If by TCP_* API you mean the RAW API in lwIP terms, yes, it's the only API I
use.  I do so strictly for performance reasons and because we don't use an
OS (in the lwIP sense of the term).  If you have an OS I'd use the netconn
or socket API?  The latter will give you pretty good compatibility at the
application level.  If you don't have an OS (the NO_SYS=1 lwIP setting)
start with the httpserver_raw demo and use that as a base for sending and
receiving data.  Just do your echo server in those callbacks.
