I just did mine last winter, took her down to bare metal, air chisel worked great. Took my carpet down to the local car wash and hung up the carpet and sprayed them down, its amazing how much dirt that carpet can hold and still not get it all out. Ordered a dye from detailking.com, it seemed to bring most of the color back. Ordered some Quietcrap and laid that down thoughout the whole floor with two layers of jute on top of that and the carpet fit back in just fine.
As for the adhesive, I followed the directions on the back of the can reading you can spay on the adhesive and let it sit for a certain period of time (I think it was about 10 mins. or so) so the jute will stick to the floor and the carpet to the jute but not permanently, it just holds it in place, I didn't want a big mess if that were to come out again for any reason, worked pretty good.
