you have some excellent domain names, alot of good potential there.. so firstly I would suggest a VERY well known business partner..someone who has proven themselves (Ron James or DNJournals Ron, etc..). These are easily million dollar a day potential.
IOrder.com: With the right business plan, you could align with takeout places, fastfood..etc and allow people to order their food online for pickup or delivery. This would probably be the best use I can think of that would produce the most revenue if you can align yourself with a good portion of food services companies like McD's, Taco Bell, Chili's..etc.
ETeen.com easy next myspace type for teens.. build in the background a way for parents to monitor their kids habits or whereabouts, and it is all the better.
ClearanceHouse Id for sure turn this into a shoppers surplus type venue. Either people can list to trade or sell of items they dont want (not auction like ebay though)
Order.net kinda speaks for itself no?
SafePC also is pretty self explanatory... give guides (text or video) walk throughs on how to protect your pc, recommend (via affiliations of course) programs and software for people to buy to help in this endeavor as well.
