Outdoor Pond Kits

you mean the liners? you can build a frame out of plywood and 2x4s for them. some of the preformed ones can be freestandings but most will need support.
 
Sure if you can support the liner with rocks, plywood or bricks or something.
 
I have seen those plastic kits used for inside. The LFS I go to has a 150 setup with a waterfall on it. He built a wooden frame for it and placed it in the store and uses a Metal Halide light for it as well. He keeps 3-4 painted turtles in there along with his koi that he sells.
 
Fish will only jump out of the pond when they are scared. If they are inside you shouldnt have anything to worry about unless a loud and sudden noise causes them to jump.

New fish that have just been added to the pond often have a tendency to jump. Use a net to keep your pond covered while your fish are still new to their environment. Use it during the first 2 weeks of acclimation to be safe.
