I tack the coils down with a large daub of silicon adhesive. They actually aren't in contact with the board but rather suspended in a cushion of silicon which prevents vibration. I solder the resistors so they stand about 1/8" above the printed circuit board, held up by their leads. I do the same thing with smaller capacitors, larger ones I sometimes tack down with silicon, like the coils.
