Macbook Air random freeze and reboot, plus other problems

Question

I've had my Macbook Air for about 6 weeks and am having several issues. It is the 13" model, special ordered with 8GB of ram so it came straight from the factory. I copied all my data over from a mid-2010 15" Macbook Pro using migration assistant, and for the most part it has been a wonderful machine. There are a few problems, however, and now it is getting more serious.
First, I visited my closest Apple store to have them look at the wifi and bluetooth connection. It was not picking up wifi after waking up, and the same for my bluetooth mouse. They replaced some files and tested it out and it appeared to be fixed, but the problem persists. At least 50% of the time when I wake it up after leaving for 30-60 minutes, I click the mouse and it wakes up, but then there is no response when I move or click the mouse again. I often have to turn the mouse off and on several times to get it to connect.
Wifi is the same, though not as bad. Probably 10% of the time, it will not connect to a known wifi spot after wake. Sometimes it even tells me that none of my trusted networks are available, even when the network I use everyday is listed as available. This is a minor inconvenience, but it is a problem I never had with the macbook pro. Instead of picking up wifi within 10 seconds of wake, it can take as long as 60-90 seconds.
Now the real issues begin. Yesterday morning I stepped away from the computer for a few minutes, and when I returned it had rebooted itself. I do not know why. Only a few programs were running, nothing like system update that would restart the computer. I did a search online but could not find anything recent enough to point to a possible problem.
Then this morning it froze while I was using it. Mouse and keyboard (both external and the ones on the laptop) stopped responding. After a few minutes of waiting I finally shut it down by holding the power button until it turned off. This was alarming, especially less than 2 months after buying the machine. I will likely make an appointment at the Apple store again but these issues happen randomly and if I can't reproduce it they have little hope of diagnosing the problem.
Has anyone else had similar issues? I have run system update and nothing else is pending. This weekend I may restore it to factory settings and load all my data manually instead of copying from timemachine, but that is a royal pain. I'm looking for any suggestions of what to do because I planned to use this computer for years and the first 6 weeks have been very frustrating.

It is probably best to return to the Apple store for assistance, however, you do have 90 days of phone (in the US 800-275-2273) access to Apple which you can use too. If you buy Applecare anytime in the first year of ownership, the warranty and phone access is extended for a total of 3 years coverage  (warranty and phone).
