Answer 2

As long as its no a reserved range, the LAN shoud still work, you will need to have the correct subnet masking in place.

In theory the Internet will work because most routers that connect you to the internet will use Network Address Translation.

Answer 3

You MUST NOT use public addresses in a local network. If any machine connects to the internet showing such an address, your ISP will disconnect you and you will be liable for any legal costs if your action causes disruption of other's service. If one of them even tries to send an email this will happen. There is no need to use public addresses, as there are thousands of private addresses available.
