Yes it does..
The CCIE Study Lab has some good excerises
The one book I have that is the best but a bit dry ( like much of cisco docs) is
Internet Routing Architectures by Cisco press
These links are from Amazon but shop around for the best deal.

I've been reading into BGP and I have one major question. If I have 2 T1s with different ISPs, how do I prevent my router/network from becoming a transit AS which would route a lot of outside traffic through it? i really only want to have redundant paths to my subnet.
It's only a concern if you have your own AS number & you setup EBGP peer relationships with the two ISP routers. If this is the case, you can use route maps with the "set community no-export" command to prevent the route through your network to ISP ABC being advertised to ISP XYZ and vice versa. This is much more complicated than it sounds - prepare yourself by reading the Cisco online documentation (starting with on BGP & expect alot of pain-in-the-rear routing issues. The quick & dirty way is to use firewalls to allow half your subnets in/out of one T1 & the rest in/out of the other. You won't get real redundancy with this solution though.
