The last time I had to do this, I disconnected the fuel lines from the rails and put them directly into a gas can.
My next step was to jack the front of the car up a couple of inches to get everything I could toward the tank sump (I leveled and rejacked one time).
I added some gas dryer and 5 gallons of fresh cheap gas and pumped that out as well. Used it in my garden equipment just like Vibrant suggested above.
Do not use this method if you suspect that there might be loose solids (i.e. rust) in your tank.
If you choose to drop the tank, it would be an EXCELLENT time to go ahead and swap out the fuel pump for a fresh one and keep the removed pump as a spare.

Pour some of the gas into a clear glass jar and let it sit. If you see dirt (shavings/rust/etc) settle on the bottom then I'd drop the tank.
That's plenty. Just remember that the particles you're looking for are going to tbe small because the fuel has already gone through a sock and a filter before getting to your jar.
