Yes.

No, but it might be easier to configure a sensible network topology
using two cards. Otherwise, you can configure a virtual interface
("ifconfig rl0 alias YYY")...

Sure.

Normally, one has one "default route", which tells all non-local
traffic to go via your preferred router. You can add additional routes
like so:
route add -net 1.2.3.0/24 router1
route add -net 4.5.6.0/24 router2
There are better ways of managing routing than this, including setting
up BGP/EGP peering with your ISPs, or some other routing protocol
(OSPF), but this should get you started....
