Hi,
You can put 2 default routes towards your ISP's next ip if the next hop ip for the both lines are different, this will do the destination based load sharing.
ip route 0.0.0.0 0.0.0.0 <1st next-hop-ip>
ip route 0.0.0.0 0.0.0.0 <2nd next-hop-ip>

Hi,
No problem, similar treatment. Follow
1. Create IP SLA/Track for both internet link
2. Break your LAN subnet into 2 smaller subnet
3. Create route map, Match with 1 subnet & route the traffic towards 1st internet link
route-map General_Internet_Traffic permit 10
match ip address 115
set ip next-hop verify-availability 10.1.1.1 track 1
set ip next-hop verify-availability 11.1.1.1 track 2
4. Create route map, Match with 2 subnet & route the traffic towards 2nd internet link
5. Configure NATing/PATing over the interface, selecting by route-map
ip nat inside source route-map General_Internet_Traffic interface FastEthernet0/0 overload

WHY two smaller subnets ???????

Hi ,
To load balance your traffic , to use Active-Active link scenario.
if you don't want than simply skip the step, configure it in primary/secondary scenario.
