Are the bubbles a good thing or a bad thing?

It shows that the pump is working and that the fluid is circulating.

Bubbles generally cause the IC to be less efficient at it's job. However, I plumbed your system to pull from the IC, so you would have less bubbles in the core. The only way to completely eliminate them is to add a de-gasser. All IC's have air trapped in the system to some extent. As the IC traps heat, air pockets (steam) will develop in the core under acceleration. Having a coolant heavy mix will help lower it too, but coolant isn't as efficient as water for transferring heat.
If you are thinking of getting a degasser, look into the Ford Racing one they used on '95 Cobra R's. It's small, and has 3/4" hose barbs...fairly inexpensive too. I'll see if I can find a link.
