It's not 100% what you have, but more how you use what you have.
Some people can make really rad music out of totally free/cheap samples/plugins. It depends a lot on what you're going for. If you're doing electronic music, there are a billion and one ways to achieve an end. Some people prefer to just go ahead and fork over the cash to go straight to the more pro-end stuff like Omnisphere, Alchemy, Komplete, etc etc while others can do really amazing work using entirely free stuff laying around on the internet.
If you're looking to experiment, Komplete Elements is fine. It's obviously not as fully loaded as the individual plugins are, but it's a lump of presets that might help you get some new sounds in your music. And there is nothing wrong with that at all, as long as your output sounds good.
If you've never used any Native Instruments stuff before, you can always download demo versions of their instruments. Not to mention they have some free versions like the Kore Player and Kontakt Player. Definitely pick those up, there's no reason for you not to. Alchemy even has a free player, and even it's got some great sounds. Again, you're limited when it comes to customizing the sounds they give you, but that doesn't mean you can't use them and make something that sounds cool.
Whatever you get, just try to learn to use it well. If you come to rely too much on presets, you might find that it hinders your creative process rather than help it. So those are the points to consider.
For $50, even though Elements is limited, that's a really good price for a decent quantity and variety of sounds, especially if you're not looking to spend $500 right this minute. You can always upgrade later.
As for helping OCR, you can pick it up by going through our affiliate links, which are through Amazon and Zzounds. I don't think Zzounds carries it, and it looks like Amazon only has Komplete 7 Elements, which is $99 (though it gives you 14 gigs of content as opposed to 3). http://ocremix.org/amazon/
Hope this info helps, don't let these guys overwhelm you :]
