The next step up would be a boot such as Boreal's Asan ($255). It's heavier than the Moraine, with a slightly stiffer sole. Not quite as comfortable on the trail, perhaps, but able to get you up pretty steep ice. Depends on how much ice you really expect to encounter - if a fair amount, then the Asan or something like Tecnica's Altitude ($275) is the ticket.
For real ice climbing, though, you're looking at a stiff, heavy boot, probably plastic. And while plastic boots are much improved, they still don't approach leather for trail comfort. So I wouldn't go there. I'd take a hard look at the Asan, find some semi-rigid crampons that will work well on steep ice (Black Diamond Sabretooth, $139), and I think you'll be all set.
