I know this is a really old thread now, but in case anyone else is reading it, you can also set "When I survey the Wond'rous cross" to this tune:

When I survey the wond'rous Cross
On which the Prince of Glory Died
My richest gain I count but loss
And pour contempt on all my pride

Forbid it, Lord, that I should boast
Save in the death of Christ my God
All the vain things that charm me most
I scarfice them to His blood

See from his head, his hands, his feet
Sorrow and Love flow mingled down
Did e'er such love and sorrow meet
or thorns compose so rich a crown

Were the whole realm of nature mine
That were an off'ring far too small
Love so amazing, so divine
Demands my soul, my life, my all

hope someone finds that helpful - personal favourite of mine.
