I have a show on Saturday afternoon as well. My plan is this...
I haven't really done anything to get ready for it yet. I want the car to look fresh the day of the show, so I am taking a half day from work on Friday so I can get started. I plan to clay the whole car and polish off the sealant and minor swirls with SSR1. I want the car looking perfect, so you can bet that I'll be paying very close attention to make sure they are gone. I've got a couple 500watt halogen lamps that I use to spot swirls and I am sure they will get a workout.
Once the swirls are gone I will use Wolfgang pre-wax polish enhancer and then a coat of the sealant. I'll wait as long as I can to put another coat on, but I'll likely put another coat on Saturday before the show. Nothing looks better to me than a fresh coat of Wolfgang.
I'll focus on the paint and the engine on Friday. The order I work in will likely be clay first and then engine. That way any degreaser or anything will not get on my nicely polished paint. After the engine is done then I'll get to work polishing the paint. If there is still time then I'll do the interior on Friday night as well. I've got a couple friends coming over who are in the show too and space and tools will need to be shared in my garage. We'll see what can be accomplished.
On Saturday morning I am taking the wheels off to detail the wheel wells, touch up the paint on my calipers, and clean the inside of the wheels and reseal them. That usually takes a couple hours to do. Then I will apply another coat of Wolfgang and clean all the glass and lenses. Likely I won't wash it again since it won't be dusty. If it is dusty then I'll just use a damp towel to wipe it off. I don't want to wash it the day of the show so that I don't have water drips to deal with. I'll also reinspect the interior and make sure I haven't missed a spot. The engine will need to be inspected as well. I use CD2 Engine Detailer to shine up the plastic and it usually looks better if you can buff it down a bit after several hours.
With me to the show I'll take some QD, tire shine and swipes (so I can shine the entire tire with tread), Invisible Glass, several microfibers, and Meguiar's Interior Detailer. Those tools should take care of any dust, bugs, or anything else that happens between my house and the show. I'll QD any mysterious drips or fingerprints and then sit back and enjoy it.

I'll put in 8 to 10 hours of detailing before the show and the car will look showroom fresh. There are areas like the door jambs that I have neglected since I bought the car, and while I doubt those areas are going to be inspected, I want them clean. If someone does open the door then I don't want anything to make them think I am less than totally obsessed about car care. After all, what kind of sponsor would I be if I showed up to my own car show in a car with dirt on it?
