Just want to know what happens if you downloads games to your hard drive and then replace it, will yoru games still be there or do you have to buy them again?

Answer:

Once you purchase a game from the PlayStation Store, then you can re-download it again. Free. There's a list of what you downloaded on the PS Store.
I did the same when upgrading to 500GB.
