Well, you know you can keep both of those warm in a wrapped towel and cooler for a few hours so give yourself that extra time. As for technique, basic seasonings. It's not a competition. It's family and friends and more likely than not, most of them aren't big bbqr's like yourself so simple basics will please most.
Keep an eye out on the weather. It's dipping for most of the country so plan a little more fuel usage. How are you monitoring your temps?
We have cookouts a few times a year. I get jitters too but more than that, I LOVE having the quiet night to myself, a cup of coffee and the smell of the cookers. It'll be just fine. You know what you're doing. Enjoy the time and Happy birthday, bud.
