Don't expect things to be much different from any other SARRC race. As Kirk says, it's actually a bit laid back since it's only a single race (plus ECR) versus the usual SARRC double. I wouldn't expect anything out of the ordinary for tech, either. You probably won't be able to find a spot with electricity by Friday night, since a lot of people come early for the Friday test day.

As far as when you'll get finished, there's a good chance that Group 3 will be run before the 11-12 lunch break, so you'd be out of tech before noon. At worst, you'd run immediately after noon, so everything would be wrapped up for you by NLT than 1:30.

There's usually a good sized field for you race with a wide range of speeds, so you'll probably need to make sure your mirrors are clean . There are a couple of very fast ASRs and 3-4 fast GT1s, so you're likely to get lapped a couple times.

Welcome to the fun!
