Answer 1

You need to create an array with values and use that.

foreach ($array as $key => $value) {
  $options[$key] = $value;
}

Then you can use $options as your options.

Answer 2

You can also use a function to return an array instead of setting each $key of the $options array.

'#options'=> function_options($param),
....
....
....

// Your Options populating function
function_options($param){
$optionarray = array();
// Populate array with DB values
.....
..... 
return optionarray;
}
