Some people seem to be blessed with the ability to naturally speak a language based on input practice alone, but I think that most people need to practice input (listening, reading) and output (speaking, writing) separately. The thing that helped me the most (at least for French) was starting a journal in my target language and adding to it every day, but anything probably works as long as it gets you writing or speaking.
Hell yeah. Few things are more satisfying than sliding a MiniDisc into a drive and feeling it click into place.
