Yesterday Marty released Snort version 2.0.3, which contains a few bug fixes. Last week Bamm announced the release of Sguil version 0.3.0. I still need to update the documentation. I had already planned a FreeBSD-only installation guide, even before all the turmoil with Red Hat Linux. I hope to have the guide done by next week.
A few weeks ago a good thread on snort-users discussed hardware for Snort and ways to avoid dropping packets.
