questions - ixtapa and zihua

I was in Ixtapa and Zihua last Feb and just loved the place. So, we're back again from Jan-Mar this year (decided to put a trip to Brazil aside) Of course I could not do it all last year so this year we want to explore both sides, esp Zihua as I really didn't have time to fully explore it.

Curious to know:

how much is the little bus that goes from Ixtapa to Zihua? what time does it run from until daily? are dogs allowed on the bus?

Is there more to do at night in Ixtapa or Zihua? any live bands? what side has more restaurants?

Are there any dog parks or such things in Ixtapa?

Any recommendations for hiking trails or biking trails (mountain biking)?

I heard car rentals are near the hotels and airport? I suspect its cheaper to rent at the airport?

What's the approximate cost of a taxi from the airport to ixtapa ? we're bringing a dog and possibly bikes (in a box) are there vans available? we were weighing the options of buying or renting bikes though and still might.

best place to get fresh fruits and veggies? and groceries in ixtapa

Any bike groups or hiking groups?

I think this site contains reference to vets and to dentists?

Any villages we should/must visit nearby?

Travel time to acapulco? by car or by bus, is it even possible to take a bus there if so from what point? is it back up and running from the past hurricanes?
