alosaurus,
I would not take it to the very edge, rather I'd allow a bit of a fudge factor. After all, slowing down a couple of miles early is going to be a whole lot safer than buggering it up and either running off the end or having a missed approach.
In the real deal this would be one of the absolutely most stressful situations ever in your whole life so don't count on being absolutely 100% on the ball. This would not be a time to learn new techniques. Be just a bit conservative and get it on the ground!
About extending the gear well above Vlo - I'd do it and never mind the damage to the fairings etc, but I would do it prior to any flap extension to avoid bits hitting the flaps.
