How many expansion ports are there and what type are they? Does the wireless LAN use one of the ports and does the video card use one also and what type of port do they use?

Can I put my songs on shuffle on this device? On my old mp3 player I can not and it is very annoying.

It lists Parental Controls, then mentions a "Guest Access". Are they the same thing or are they separate? Our current router has guest access, but I have to babysit it when we have guests log into it. I would like a router where I can set up control over what times certain devices can access the internet. Preferably, only having to set it up once and not each time a user logs in. (IE. lets me kick the teens off the wireless on their phones at midnight, disables the bluray at midnight and/or disables certain laptops at midnight.)

I have a 9 and 12 year old that need a new quality headset (already broke two and want a sturdy one) with microphone for Rosetta Stone. I worry that they will not adjust to a small enogh size (although our family tends to have larger head sizes) for the microphone to be at a good level for speaking. The previous cheap ones we had were not specifically kid sizes but seemed to work.
