If you are already brewing on a larger scale, the list is probably only the following:
1) the smaller fermentation vessel. I use:http://www.naturalwanderings.com/wp-content/uploads/2011/08/Empty-apple-juice-jug.jpg
from a local grocery store. If you don't like apple juice, then that might not be as win-win as it was for me.
2) Smaller sized rubber stoppers. #7 fits 5 gallon glass carboys. #6 fits my 1-gallon jugs. If you can bring the jug with you to size them right, that will be best.
3) a kitchen scale that can weigh out the much smaller masses of hops. You may find yourself trying to accurately measure out only 3 or 4 grams of hops sometimes, so it needs to be sensitive and accurate.
I have been using this one, which is okay, but its accuracy is probably +/- 1 gram, so I'm not completely happy with it:http://www.amazon.com/EatSmart-Precision-Digital-Kitchen-Scale/dp/B001N0D7GA
