vent piping

We are remodeling a bathroom and have some questions regarding vent piping.
What is the maximum horizontal run between the trap and the vertical portion of an existing vent?
We are trying to vent a whirpool tub. There is an existing toilet stack eight feet away, however, the vent pipe needs to travel around the perimeter of the tub to reach the toilet stack resulting in a total distance of 15 feet.
Second question; we are installing a secondary washer and dryer unit one floor above an existing unit that will remain in service. Can you recommend the best way to tie the new vent to the existing washer and dryer vent. Would you recommend a wet vent for this application? The existing washer and dryer stack does not directly vent to the outside, but rather ties in through a horizontal run via a toilet stack in the adjacent bathroom six feet away.
