7 week old puppy around my old dogs

Question
i just adopted a full breed golden retriever (male), he is a delight. but i have 2 other dogs, one is turning  9 years old tomorrow, and he's a male, and then the other ones a female and is 3 years old.
now, i know he is teething and you have to have patience and all, but he runs around the house chasing the male dog into terror, by biting his tail. it was cute at first, but now its like a barking war, my older dog doesnt want to put up with it, and he will continue to bark for 10 minutes.
another thing im worried about, is his attitude towards me. i tell him no, and he thinks its funny and bites my finger, although i do think the finger is pb why he's doing it. he also loves to bit my hear when im laying down or my ears. i have a bunch of toys for him to chew up on, and play with. what do i do? i know youve heard this about a gazillion times.
other than that, hes a great dog.
please help!  

Answer
Maybe not a whole gazilion, but enough I will start with my stock answer.
Young Labs, which I know best, and other puppies tend to very bad about
biting.  You see a litter of them, and all the ones that are awake are biting
another one or themselves.  I am not even sure they realize that when they are
alone, if they quit biting, they would quit being bitten.  At 3 to 4 months
they are getting their adult teeth, and it seems they spend every waking
moment biting or chewing.  One thing you can do at that stage is to knot and wet a piece of cloth.  Then freeze it.  The cooling will soothe the gums.  Only let the puppy have it when you are there to watch it.  I maintain a Lab's favorite chew toy is another Lab.  Otherwise they settle for any person they can.  They keep hoping to find one that won't yelp and jerk their hand away, or growl "Bad dog." and clamp their mouth shut.  Then offer a chew toy.  They keep trying despite hundreds of corrections.   Another good technique is to quit playing and go away.   Be sure to praise them when they are playing nice and not biting.

You just have to keep on correcting them, hundreds of times, not dozens.
Provide sturdy, safe toys such as Kongs and Nylabones.  Avoid things they can
chew pieces off and choke on them.  Keep them away from electrical cords.
Crates are essential for most young Labs and other dogs.  

The pet stores are full of toys that many dogs will quickly chew up into
pieces they could choke on or cause intestinal blockages.  If you are not
there to watch, stick to sturdy stuff such as Nylabones and Kongs.  Keep a
close eye on chew toys and quickly discard anything that is coming apart in
pieces.  Rawhide is especially bad because it swells after being swallowed.
These problems are the worst with, but not limited to, large, aggressive
chewers such as Labs.

He sees you and the older dogs as replacements for his litter mates, and expects everybody to enjoy the biting.  At 3, the female may indulge him.  For the male and you, it is just a matter of constant corrections.  Just react the same when he goes for the male as for your or the sofa.  Tolerate the older dogs giving him warning snaps if they do.  

We have brought 3 new puppies into the house plus visitors since Aster the grouch came to live with us 2 1/2 years ago at the age of 10.  We work with her, correcting the puppies when they go after her.  Puppies need to learn some dogs aren't interested in playing, and people will not tolerate biting.  It just takes persistence.
