ConnectTimeout - maximum period of inactivity while TCP connection is
being negotiated.
ConnectionRequestTimeout - maximum period of inactivity waiting on a
connection lease request. Used to be called connection manager timeout.

See above.

One can set a desired protocol version directly on request message
instances. The parameter is completely superfluous.

1. IOReactorConfig defines global (client level) defaults used by the
I/O reactor when initializing new connections
2. No longer supported as of 4.0 GA
3. RequestConfig represents request level parameters. Socket and connect
timeout values, if non-zero, override those used by default.
Hope this helps
