building code questions?

So I am building an interior set of walls on a concrete slab. I was told that I had to put a piece of plastic or sill gasket under the pressure treated bottom sill. Is this correct. Is there a code that states that you HAVE to do this?

Number two question regards floor joists. I have a set of floor joists that do not end over a beam. Looks like they scabbed on another 5 foot piece of joist and used that to continue the joist over the beam and then nailed it to the butting joist that continues over the first beam and then ends over a built up beam. Looks like they missed the first beam by about 6 inches. I think because they put the beam pockets in the concrete walls in the wrong place. As Maxwell Smart would say....."Missed it by that much." Odd thing is that the joists are only around 15' long. Curious as if they would have used 16'ers they would have made the beam.

Oh and they used 2x10 joists. Span is 16' between beams two story building, and the carrying walls are supposed to be over the beams....
