The one time I don't recommend simply dropping a show and someone takes it sarcastically anyway. Oh well. I don't think you should worry about learning any new tricks. You've only got a week.
What you listed are six tricks with no connection whatsoever, and no presentational theme to tie them together. With CO taking about a minute for most people, Think Stop, Betwixt, Biddle all being about 2 minutes, Whack Your Pack being about 2.5 ... that's 9.5 minutes of material. I'm not sure which 'cannibal' trick you're referring to but the ones I can think of are anywhere from 1.5 to 5 minutes. So overall you're looking at (judging by average performances, since I don't think I've seen any of your performances) 11 to 14.5 minutes of material. That's also assuming you've got the performance experience not to rush through anything.
So you need anywhere from 5.5 to 9 minutes of material to meet the minimum amount of time you're expected to perform. And you want suggestions based solely on a list of tricks which give no indication of character, style, experience or resources available. We also don't know what environment you'll be in. What lighting, is there a table, etc?
You've got a bit of mind reading in there with Think Stop, so you could throw in a three-phase mind reading bit. The first using a peek, the second using a force, the last using K.E.N.T. That should be at least four minutes.
Betwixt and Biddle are too similar, don't use them in the same show unless there's a presentational reason that makes them build off each other some how. I would use Betwixt as it probably has more potential to fill time.
I wouldn't use Whack Your Pack in a professional show unless you've got a way to avoid having to pick the cards up afterward. You do not want to look like you're chasing a chicken.
If you've got Greg Wilson's Revolution, that fills up a decent amount of time and is a way to show all the cards without having to say, "Look all the cards are different." It's not technically difficult but if you don't know it already you may not have time to get it down. Mostly because the video has some flaws in it, which I have addressed in reviews which I think I posted here at T11. If not, I know I posted it on Ellusionist.
I never actually open with Chicago Opener, personally. I used to use it third. Because by then I'd done tricks which show all the cards, front and back, and I allow the spectator to take the deck to make their selection. It takes longer this way and it's more impossible.
If you've got Tony Chang's ChangE, you can do his "Defective Deck" routine to open, go into his DVR (The Joker is already set aside), then go into Chicago Opener.
If you have 10 people then you have enough to do a Tossed Out Deck. That would fit together at the end of the mind-reading section I mentioned above, but you might want to cut out one of the other phases as it will probably be getting redundant by then.
You could also do an ID routine, but you'll have to figure out how to make it seem magical with all this sleight of hand going on.
There. Lots of suggestions.
Oh, and the biggest one. Don't book a show if you don't have it already written.
