It's a good idea. Landscape fabric keeps weeds from growing up through the gravel and prevents the stone from slowly sinking into the soil underneath. It's inexpensive, easy to lay down, and adds years of clean, low-maintenance performance to your pad.
Lay it down before you spread the gravel, overlap any seams by at least six inches, and you're set. It takes maybe twenty minutes and saves you from pulling weeds through stone for the life of the building.
