1 my guess: after a wheel well fire there may be some fuse melt,so eflated wheels. Autobrake 3 means increased braking on the wheels,no matter reversers.I'll use autobrake 1 or maybe 2 with full reverser to minimize braking on the wheels. Just a guess,though.
2)SINK RATE ---- TERRAIN----PULL UP in this order (assume gear & flaps up)
3)The visual manouvering area for a circling app is determined by drawing arcs centered on each rwy threshold and joining this arcs by tangent lines.The radius is based on a/c category.( usually 1.5-2NM)
The obstacle clearance in this area is 300'.
(find all these in jeppesen gen,I think)
4) as said by b735 and ddg
