Amazon swords are not very light demanding. They will do fine with a twin fluorescent bulb strip over the tank. They like a deep and rich substrate. Use some rocks to terrace your gravel so that it's about 3 inches deep where you want your sword. If available put a clay ball under the roots. I also use Jobe sticks for ferns (avaialable at garden stores) about every two months.
When planting snip the roots to about 1.5 inches and make sure they are not bent double during planting.
If the sword likes your setup it will grow to about a one foot diameter, so take that into account with your aquascape. I think a sword in one corner and a red lotus in the other looks good, as they are both large plants, but very different in appearance.
