SiLK is a powerful toolset for analyzing netflow and pcap data generated from TCPDUMP. It's a slight learning curve, but worth it IMHO. Fairly good documentation too.
From that toolset, you can use "rwptoflow" to generate flow records from TCPDUMP to SiLK format.
You might also look at "softflowd"  or similar tool to export netflow records from whatever box your using TCPDUMP to capture data. Then you can output netflow records directly to most of the aforementioned netflow packages. Having the actual packet data is useful later once you've found something suspicious, or for snort.. etc.
