Wow, so many odd questions I don't know even know where to start.
1.) You need to train for whatever is most important to you. If I ever did something like that I would probably train very hard for it for about a month, maybe two in terms of cardio and conditioning. There is a chance you will need to take a few extra days off here and there if you're doing intense conditioning work, though. Do NOT stop the program or stop lifting, that makes no sense at all.
2.) It would look like an arm day with any other program, or you can just add tris after your benching or biceps after your back work. There are a lot of threads about arm training and you can find those yourself here or in the T-Cell.
