First, quit spraying the dog with water. This is a poor training technique.
When she begs, just simply ignore her. No need to spray water. If she becomes more insistent, then a firm "No" should suffice.
A dog will always sniff.....it is within their instinct. No need to spray water.
Getting on furniture is the same. Just block her access with a firm "No". Or if she is already on the furniture, just a firm nudge to remove her with the "Off" command.
Do not forget to reward when she gives any sign of compliance. Reward can be treat, pet, play.
Raw bones are acceptable. Just be aware of the size and type. No weight supporting bones or joints. These are too hard and could break teeth or splinter.
Jack Russel Terriers are high energy breeds. They need the activity and exercise. They are the 460V breed of the terrier group.
Frankly, your thoughts about the current dog rearing the pup is fantasy. Your current dog will only see the new dog as a trespasser on her territory. Remember, dogs do not harbor emotions like jealousy. This is a human condition. Although, they may learn to be "pack" mates. Get familiar with techniques to introduce a new dog into the household.
I would also suggest to learn proper, kind training techniques. Dogs are smart, terriers are generally some of the more intelligent breeds. Most terriers do not respond well to punishment based training. Actually, very few dogs respond well to punishment based training.
