One question per post please.

The only requirement is that they have a unique MAC address.
With Ether-switches and trunking it is possible to improve 
bandwidth in some cases.   These are the cases where if you
have to ask why or how you should not.

The most common case for the use of two nics is to access
two nets.  It is not necessary to route between networks.
One strategy is to dedicate a net for storage traffic and
another network for some other communication traffic.

The second common case is to act as a network gateway, firewall, NAT
or bridge etc...  i.e. a router.
