Webpack most assuredly does contain both a synthesizer (XST) and the
PAR tool.  They do different things; the synthesizer is not reponsible
for place and route.  Anyhow, I've used Webpack quite extensively for
development with a Burched B3 board and a Spartan 3 starter board
for several years, and there weren't any missing development tools.

And as I've mentioned here quite a few times, if you use Webpack 6.3i
with a service pack installed, you can even target the XC3S4000.  The
drawback is that Webpack 6.3i is not available in a native Linux version,
so you have to run it on Windows or WINE.  (I used Windows in VMware.)

Webpack 7.1i is available in a native Linux version, but the largest
Spartan 3 device it will target is the XC3S1500.  Many of us hope that
Xilinx will add support for the larger S3 parts in 7.2i.
