I am not sure, but I think the second command should read:
ipchains -A forward -s 192.168.0.0/24 -d 0.0.0.0/0 -j MASQ

You can also have the local clients go directly to your ISP's
DNS server(s). Makes thing a little simpler.

If the gateway does not work, you're probably right.

ip_forward must definitely be set to 1. That was the last I needed to
set to fix my setup ;-) I guess your system scripts does not set it
properly, try to fix manually and then fix or simply add the proper
command to your favorite system script (maybe rc.local).
For the gateway, mine is set to the Internet side, try to manually
set it and see if it helps.
To perform tests, try to use a simple ping command in NT (use the
command line window) to an IP address (may be the ISP DNS server)
and look at ifconfig to see if the Internet side tx counter increases
(in case you still can get it to work).
