Hi Chris, I use a 5x powermate for planet imaging and found that it makes a huge difference. I had a Meade 3x barlow before but it was completely useless compared to the powermate. I can definitely confirm that a ToUCam can indeed capture a lot of details. Here is a link to my best Jupiter image:

I haven't been able to surpass it since, but have come close on a couple of occasions. I think this is pretty much as far as a ToUCam+powermate will stretch.
Another one, though not quite as good:

Good luck with your imaging. Yours look quite like mine did before I got the powermate, so there's lots of potential.
