How long was it in the primary? For a bigger beer I like to have mine in the secondary for 2 months, bottle and store for a few more months. I would think you could bottle after a month but it may be clearer with a second month.
It should be good for at least 2-3 months in the secondary without reyeasting. Adding more yeast tends to speed the carbonation process (sometimes), but won't be necessary given the relatively short fermentation you're planning.
