I'm not sure,but my spring is in the way when I pull the pin to open this thing up,is it supposed to be in the way?(and in the way of closing too) Am I missing something? Has something flown away on me?

The way I'm understanding you, the buffer pin and spring may be missing so it doesn't retain the buffer assembly and action spring in the buffer tube while you lift the upper receiver from the lower.
When I try to open it..the spring wants to fly away..or jams is this normal? Or when I close it..I have to push back the spring with my finger...hmm.
