How do i bring an orchid back from near death?

ok ive had this orchid for about a year now. it was doing great when it was in bloom. but shortly after it started to lose its flowers it started getting "sick". the leaves turned yellow and fell off. then it started to shrivel up. i trimmed all the dead leaves off of it(as they died). i was told to tae it out of the pot i had it in. then wash the roots compleatly. then cut off any dieing roots. so i did there was only one little(about 1") new growth so it is still alive. (i think?) i put the " baby" with fresh trimmed roots in a plastic pot with holes cut in it for a basket looking planter. i then put a few rocks in the bottom(bout an inch or so). then a little spanish moss(again bout an inch) then i filled the rest of the plant with coconut husk cut into cubes. im wondering if this will suffice to return it to its beauty again? and how much light should it get? im pretty good with plants but this one gives me a headache! but i do love it so!!!
