What tools do you recommend for requirements management?

The most common tools used are word processing documents like MS Word, spreadsheets like MS Excel and diagramming tools like VISIO. My recommendation would be to learn how to walk before you run. This website includes an MS Word requirements document template that you could use to document process flows and requirements statements. After you have some experience doing things "manually", then you're ready to look at tools. Unfortunately, I don't recommend any automated tools at the moment, However, I'd like to hear your experiences (successes and failures) using automated tools.
