Well I wouldn't consider myself a vet, but in answer to your questions . . .
It depends. As others have said, just how close you can get to the cache depends on the coords of the cacher who placed the cache, satellite coverage, etc. I've had caches that I've zeroed in on with no problems and other caches that were off quite a bit . . . either due to my GPSr or to the cacher's coords. In general it seems as though I will be anywheres from 5-20 feet in general.
I think the best advice for locating a cache is to do what others have said . . . when you get to the last 100 feet or so start looking with your eyes at the terrain instead of looking at the GPSr. Look for things that may be out of the ordinary. If you've read the clue look around to see if that helps.
I will say that when I'm hiding my cache I try to go out on two to preferably three different times to get cords which I then average out myself -- along with the GPSr averaging them. I jot down the numbers when I first arrive and then jot down a few readings in the next few minutes with the unit at a standstill. I've done this before and in one instance the coords I had on one date were quite a bit off from the other two days . . .
When hiding my cache I also try to provide a hint . . . I figure if people want to use it they will and if they want the extra challenge they will not use it . . . besides I want people to find my caches.
