I use pivotal tracker to record tasks and then prioritise them and work through them. It's good in that, if I don't work on it for a month or two then nothing changes. When I start working on something... everything changes and the estimates come forward and it auto-generates the idea of a sprint, spacing work out over coming weeks based on your velocity. It's nice.
