Have both send full routes, then filter what isn't needed.
Level3 has an excellent set of BGP communities that allow a good
deal of tuning... kudos to Kevin Epperson for designing and
implementing that. I'm actually surprised that you have 2x
Level3 T1s; they don't like selling smaller circuits these days.

Indeed, but then I could be biased. ;-) Of course, a client
without any BGP experience tried turning up a session on their
own, and started sending full table to the new upstream; luckily,
the upstream was clueful and caught it. In short: maybe I'm not
biased. ;-)
To the original poster:
Give a good deal of thought to the BGP config before beginning.
Confederations, proper ACLs, loopbacks, blackhole routes,
communities, et cetera ad nauseum all are things I think should
be part of _any_ basic config.
I also suggest using two routers for reliability... in which case
the example that say "nail routes to loopback" are wrong.
Finally, don't redistribute routes unless you know what you're
doing. Keep your eBGP clean and your IGP lean and mean.
