Answer 1

just click on cancel and when you are done with setup, you can update and install it later.

from official android site :

To open the SDK Manager from Android Studio, click Tools > Android > SDK Manager or click SDK Manager in the toolbar. If you're not using Android Studio, you can download tools using the sdkmanager command-line tool.

When an update is available for a package you already have, a dash appears in the check box next to the package.

To update an item or install a new one, click the check box so it shows a checkmark. To uninstall a package, click to clear the check box. Pending updates are indicated in the left column with a download icon . Pending removals are indicated with a red cross .

To update the selected packages, click Apply or OK, then agree to any license agreements.
