Time Machine first timer

So i just set up time machine on a 1T HD external firewire(also came with an esata card!!) My question is that i have some programs on here that i got because of my job. Does time machine back up my programs as well? Like if i crash and lose everything will i be able to go back in time(funny apple people) and save my final cut HD program? If the answer is no then how do i save a program that is already installed on my mac? Can i put it on a DVD?
