I'm hearing good things about TraceAnalyzer, a tool that reads SQL Server trace files and allows you to view and sort the data. It's free and can be helpful, according to all the reports I've heard. You might want to check it out at

I'm a big fan of Bill Graziano's ClearTrace tool (available at http://www.scalesql.com/cleartrace/download.aspx). So if you've tried both, I'd like to hear your assessment of the two tools.
Many thanks,
