Marcus, if you just follow the two points I mentioned above, you shouldn't have anything to worry about. One other note: marmots love salt, so if you have any clothing items with dried sweat, put those in your bear can or take to the summit with you. I have a set of trekking poles with badly-chewed wrist straps to prove it.
Advice for a first time camper at Trail Camp: it's all rock so you cannot stake your tent. Leave the stakes behind - it's just useless weight. Be sure to take about 30 feet of extra cord with you to tie your tent guylines to rocks. It can be very windy at TC and you want to secure these lines very well.
Good luck and enjoy the experience.
