avatar questions:

1. how were the sky bisons able to reproduce when there was only 1 left
2. is guru pathik an energy bender?
3. zhao hinted that uncle iroh had a trip to the spirit world, i wonder what for

Answer to the first question from the avatar wiki:

Aang also found an island filled with lost flying bison, along with a new type of winged lemur, the ring-tailed winged lemur.

1. aang found a herd of wild sky bison
2. i would assume no but he is pretty darn close thought it was said by the turtle humans forgot energy bending when they transformed it into element bending
3. i missed this one completely

2. i mean he was able to communicate to appa by just touching him, kinda like the turtle

so about all the stuff that happened between the last air bender and legend of korra... did they just lay out a story plot? was there some kinda show i missed or was there comics or something like that?

nope, i googled all the inbetween info lol

also there will be another season after book 2 which will also be 26 episodes so in total 52 episodes :).

there are manga/ comics i believe

Guru Pathik isn't an energy bender but he can meditate and wander through the spirit world like the Air Monks in the past. The first energy bender in the era is Aang.

The comic/cartoon is base of a book.
The comic concentrates on the making of Republic City.

how was he able to show appa the spiritual energy that connects him to aang (making the path that led appa to ba-sing-se)
