Hi Daniel,

you can also double-click on your background-layer, so it becomes 'layer 1'.
The background layer cannot have transparancy, but layer 1 can.

Now select your Alpha Channel like before, so you have the marching ants.
Then hit the little "add layer mask" button in the layers-palette.
You should have transparancy now. and You can safely delete the fourth channel.

Since After Effects understands PSD files pretty well, it will see this transparancy as an alpha channel even though it is not explixilty a 4th channel.
