While the first three parts where actually bogus and solely for entertainment purposes, the following two recommendations are serious, possibly helpful for non-statisticians, too – and actually free.

• A very helpful software tool for data entry is EpiData. If you are working with manual data input (e.g., questionnaire data) you should definitely check it out – unless, of course, you already know (and use) it.
• The Firefox extension is Zotero is capable of collecting, managing, and citing research sources. It rivals common citation software, not only because it is free, but also because it is very easy to handle. I got to know Zotero just two days ago – thanks to Biddy for the hint – and felt at home with its usage in a matter of minutes.
