Visual Studio 2015 Xamarin Forms Tools->Android-> all grayed

I am trying to get Visual Studio 2015 set up to do Xamarin Forms.
I have two issues (that I know of)

1) When in VS I navigate to: Tools->Android-> all the options are grayed

2) When I do an Install or Repair I get messages indicating that it had problems downloading Android SDK Setup (API Level 19 and 21). Same thing for 22 and 23.
I have what looks like an Android SDK at :
C:\Program Files (x86)\Android\android-sdk
And there is a link to it in Tools->Options->Xamarin->Android Settings.

Any insight is appreciated.
