Figured I'd put up this picture for you guys to look through. They want too much IMHO but a different set of eyes always helps.

 

Wampa, y wing, Harry Potter green roof, taun taun?", jar jar's kind orange "horse", green jeep from toy story, sandtrooper's beast maybe, snowspeeder, alien quest (is that what this UFO is called?), yellow Jedi star fighter,  big round yellow plate with sticker (or printing) from HP( right by yellow Jedi fighter ship),another known SW ship hiding behind the bin with tan plates (below snowspeeder) another HP building below UFO. Im bad with names, hope it helps. 

Star Wars wise, I think you have at least the following:

7115 Gungan Patrol

7256 Jedi Starfighter and Vulture Droid

8089 Hoth Wampa Cave

9495 Gold Leader's Y-Wing

75049 Snow Speeder

75051 Jedi Scout Fighter

75052 Mos Eisley Cantina

75096 Sith Infiltrator

The tauntaun could be from a few different sets. Some of the sets could be older ones than my guesses.

I see power miners 

alien conquest

ultra agents

HP

Star Wars

Depending on completeness and minifigures could be a nice lot
