I've played around with a few different software controllers and the only one I've found that has everything I'm looking for is the Martin Lightjockey. Unfortunetly, it won't work with your DMX interface, you'd need to buy theirs, which is a tad pricey. But considering the cost of moving lights...this isn't priced so bad, for all the control you can get. The newer version has 2 DMX outs, for running 2 separate DMX universes. But it seems you can switch one of the outs to be a DMX in (you'd just need a sex changer), so if you have an existing "manual" light board, like I do, you can even use that to control certain features of LJ. I'd highly recommend LJ if you've got the money, and you plan on expanding your setup in the near future. If you're not and you plan on only sticking with a couple moving lights, perhaps a non software based controller would be better. They do make controllers specifically designed for moving lights that seem to offer up a lot of options. Going with computer control may be overkill for just 8 cans and a couple movers.
