Oak chips use

[Math0]

Hey all, I did a couple times the same recipe now and I would like to try something different with it. It's a medium to sweet stout. I bought a couple oz of oak chips and now I'm wondering what exactly should I do with them. How much should I put in a 1 gallon test batch? I must say the beer is done fermenting and would be ready to keg. I see a lot of people soaking them in bourbon, how does it affect the flavour? Also, how long should I keep them in, or could I leave them until I finish the keg? Finally, are they reusable for a same recipe after? I'm thinking of a cedar plank when cooking for example.

Here is a link to a five gallon recipe that may help with some decisions.

I have never done a BBP. Just had the first taste of a friends.
