It looks good for the information given above, though the OS settings and other computers' settings are all correlated.

I forgot the webserver. My Webserver has two network cards.
One is set for static IP from ISP, and it´s responds for my website www.website.com
ISP IP/24, gateway from MY ISP and DNS from ISP too.
The other network is set for internal access.
IP 192.168.0.10/24
gateway - blank
DNS - Blank

I would agree to put your gateway as the first or last IP address.  Your switches, routers, WAP, etc. next.  Then servers.  Then printers.  Then leave a gap for growth.  Then put your workstations IP addresses as the largest pool.  Keeps things simpler, as you can create firewall rules or service rules by IP address range versus individual addresses in a list.

Is your web server inside or outside of your firewall?  If inside, you don't need two NICs.  Your internet router would open just ports 80 & 443 and NAT them to the server on the LAN.  Safer than putting in the wild, then leaving a direct hard link to your LAN.
