What are all of these entries in my keychains?

hi,

I bought a Macbook Air last winter and haven't used it much (preferring my old MBP from 2009). I see now when I started it up in January it created 2 new keychains "Login" and "Local" that have 100s of keychain entries I didn't make and didn't import from my old Mac. I do not use iCloud and have everything iCloud related turned off/disabled for every setting I could find (although somehow it seems to be sucking up my keyboard preferences from my iphone and pushing it to this Macbook Air!)

Here's a sample of the type of things I've found in the keychains. What are these? Can I delete these? Why aren't these going into a "System" keychain like on my old Mac for things like networks etc.? Can I delete these keychains and import my keychains from my old MBP or open them remotely like I can with my old MBP and keychains stored on other volumes?
