Hi,

1) This is used only when there's a router between your DHCP server and your clients. Requests are in broadcast, broadcast doesn't pass routers.
2) No problem, assign them a static IP and they will never receive a DHCP address.
3) There's not the best answer. Let's say that if you network has 10 clients, you can set a lease of 1 hour and everything is ok, but if you have 100 clients the story changes. If your clients are almost the same everyday, you can set a lease of 6 days which is ok.
4) No, but pay attention to the scope. For example, if you set a static IP to your server (let's say 10.0.0.100) and in your DHCP you set a pool from 10.0.0.50 to 10.0.0.120, the dhcp server can assign the IP 10.0.0.100 which is in use by your server. This prevent users from accessing the server (IP conflict). You must exclude static IP from DHCP range. You DHCP DOES NOT KNOW anything about your network, it simply give an IP (if there's one free) when requested.
5) ??? can you describe your problem?
6) - waiting for answer from point "5" -
