I think bottling bucket or in keg, no need to secondary, wood chips either iirc. I need to check but pretty sure. I will get back when i check my resources. The chips get tossed in fermenter, if you want oak and left a week or whatever. For the bourbon i will check my recipes and resources as well on amount, but taking a pint and experimenting to taste could work too. Personally I have come to enjoy splashing the beers. You leave the beer as is and then splash it with whatever you want/have when you drink it. Sometimes I splash in a little more, sometimes a little less. Sometimes red wine, and sometimes bourbon.
Remember a little goes a long way and I'll give you a good starting point. There's some debate on this and I know a lot of people say just use whatever cheap stuff you can find, but I don't believe that at all. And the better bourbon you use the better it will be. If nothing else just from a confirmation bias that you made something of quality. I try to not get to tipsy when I taste to amount. Also helps to have a friend taste. Sounds like a great beer.
