Tracking Software Advice

Sorry if this is not the appropriate place for this post, but the Software forum didn't seem to address this and this was described as the 'newbie' forum so...

I'm new to poker. I've been playing for less than a month and been having a good time, but I want to start to really work on my game. I've read a couple of the 2+2 books(and re-read them, and then re-read them, and slept with them under my pillow). This has of course helped my game but now i'm wondering if it is time to buy tracking software that I read about.

Is it gonna do me any good at this stage of my play?

Is PokerTracker the only software out there? What other options might there be?

Thanks In Advance,
Kevin
