There is no way 100 stolen bases are worth 30 HR's. Because even if he is thrown out only 25 times (80% success rate), that's a net 75 bases gained. And those bases do not advance any other runners.
I'd rather have Taveras than Hamilton for a bunch of reasons; however, Hamilton's value will come more from his general running on the base paths (getting those extra bases on his and other's hits) than his stolen bases. It's actually going to be hard to measure the impact he has on the bases, since there really hasn't been anyone with his speed, in the game recently.
