Is there any actual evidence of the 'west' being the enemy of Poland in communist times?
You should read about Cold War :-) in 60' there was almost WWIII. Another thing is that war between Poland and Germany in fact ended in 1990, because previously Polish west border wasn't recognized by west Germany... Heh, loking at things from current perspective, it seems that Europe before 1989 was really weird place...
What percentage of the communist Polish armed forces were conscripts rather than proffesional sodiers, any ideas?
Don't know exact number but most of it was conscription. PRL army size were between 200000 and 400000 soldiers (depends when), with much more ready for draft with military training. Add to that a few hundreds thousands Russian soldiers which stationed in Poland.
Anyway, I'm glad that conscription ended, but I think some kind of territorial defence should be created which could be used in case of natural disasters.
