Adobe CS3 options a little confusing

I'd like to upgrade my copies of Photoshop and Flash and get Adobe Lightroom. Adobe has an offer for Photoshop and Lightroom and another one which includes Flash and Photoshop, but the only way to do what I want is to probably buy the Photoshop & Lightroom deal and then buy Flash separately. When you do that, you pay so much money that it seems better to buy one of the package deals and purchase Lightroom by itself. That might be the better move, but there are too many deals and packages that it's all a little confusing to me. And some of them aren't available yet, which makes it even more confusing.
