Styling the Toolbar

Question

I'm trying to get a transparent Toolbar over the top of my Navigation Drawer. I had it working pretty nicely until I had to put a Toolbar in my layout so I had a reference to it, to pass to ActionBarToggle.

Styling the Toolbar is awful. I've played for hours and nearly got it right now, but there are a couple of things I cannot for the life of me fix.

1 I want the hamburger icon and the option menu icon to be white.

2 I want the Toolbar to be visible over the NavDrawer.

3 I don't want any shadow or elevation around the Toolbar.

These three things seem massively improbable.

Here is my Activity Layout.

<?xml version="1.0" encoding="utf-8"?>

If anyone knows how to start to get what I need.. It seems impossible at the moment. I actually had it nearly perfect, until I had to declare a Toolbar in XML, since then, themeing it has been near impossible. All to get the hamburger animation..
