Hi, I haven't made this specific kit, but I have to ask, where did you find it?!! I have been looking for St Peter's kits without success (I'm in Canada).
As for bottle priming, I always use the priming calculator at tastybrew.com, just input your parameters to get the amount of priming agent to use (It will give results in various sugars so you should be able to find a calculation for what you are using). It's been reliable for me.
As far as the priming process I always batch prime instead of doing each individual bottle. I bring 2 cups of water to a boil on the stove and add in the priming sugar to dissolve, let it all cool down to the same temp as the beer, then pour into the fermenter and stir very gently to distribute it. This gives me very even carbonation. Some people swear by the carbonation drops too, but I haven't tried those.
Good luck!
