what the others said - you bottle when the beer is ready, not by a calendar. yeast works on its own time. maybe 2 weeks is plenty. maybe is isn't. only one way to know: 3 days of consistent hydrometer readings.
secondary will not stop fermentation, it'll only slow it down. so if you bottle before all sugars are fermented, moving to secondary is a bad idea since there is a better chance of those sugars making it into the bottle and creating bottle bombs. that's why you shouldn't transfer to secondary (or bottle) until fermentation is complete.
some people swear by secondary, but there seems to be an emerging trend to skip it unless there is a specific reason: adding fruit, extended bulk aging (6 weeks or more), dry-hopping (although DH'ing can be done in primary just fine), adding wood chips, etc.
