We have this exact setup. Unfortunately you can't load balance using 2 different ISPs unless you have an AS (Autonomous System).

What you can do is point some computers on your LAN to one gateway, and point the others to the second.

Reading a book on routing would also be a good idea. "Designing and Implementing Linux Firewalls and QoS using netfilter, iproute2, NAT, and L7-filter" is one of my favorites because is has some very interesting case studies.
