* Is the 3 week in primary recommendation appropriate with this smaller batch/entire yeast pack combo? I have come across info regarding pulling beer off the yeast cake sooner.
* I would like to reuse the yeast and am considering racking my next batch right on top of the existing yeast cake (it will be another 2.5 gallon batch). Are there any special considerations I need to take since its a 2.5 gallon batch?
* What type(s) of follow-up beer would you suggest? I think I've read that going to a darker style is best, but what would work best?
* How many batches can you do on one yeast cake?
* This seems to be the easiest way to reuse, are any of the other methods better/easier?
You can leave the beer in the fermenter for three weeks, no problem.
I would NOT pitch the whole yeast cake in another batch, though! That'd be way to much yeast. Mrmalty.com has a "yeast pitching calculator" and one of the choices is "repitching slurry" to tell you an ideal amount to use. I use that all the time.
If you absolutely want to use the entire yeast cake, you'd want to at least go from a "small" beer to a bigger beer. I have done that in the past, using the first beer as a starter to a very high OG beer for the next one.
What I'd probably do is even easier, though. In fact I just did this yesterday, and I have 6 jars of nice clean perfect yeast. http://www.homebrewtalk.com/f163/yeast-washing-illustrated-41768/
