When fermentation is complete, split 2 vanilla beans lengthwise. Scrape all the seeds and "gunk" from them and add it to the fermenter. Chop the beans into 2-3 in. long pieces and add them, too. Leave in secondary 10-14 days, then taste. You want the vanilla to be a bit on the strong side since it will fade. If the vanilla flavor is adequate, rack to bottling bucket or keg and add approximately 375 ml. of Jim Beam Black bourbon. You don't need to use an expensive bourbon, and you don't want to add a lot. The beer shouldn't scream "BOURBON!" at you. You should have an integrated flavor of the chocolatey porter, vanilla, and bourbon. This beer does not benefit from extended aging. I prefer it within a few months of brewing. The FG should be in the mid-high 20s, so don't worry about trying to get it lower.
