Love Amarillo. Great passionfruity/citrusy taste, perfect for single hop brews.
Don't be too quick to bottle. If you're anything like me, you checking up it every time you go past, seeing if it's still blooping... It's fine. And it doesn't hurt to let it be for a while longer after it stops (ie a week or more). According to some guys on the internet (which includes this magnanimous bunch), your yeasties still have some work to do after all the sugars have been converted. You might want to raise the temp up a few degrees for a couple of days for a diacetyl rest before cold crashing (if you care for that).
What you really don't want is to have unfermented sugars present when bottling, as that's a pretty sure method for some bottle bombs.
As for the bottling method, I just bottle from the tap, making sure it doesn't splash around to much. I wouldn't worry about racking/siphoning unless the trub layer is above the siphon.
