I think the soil problem you've described is the issue (why Poa a. took over and why desirable grass didn't establish).
I would work on the soil. Use a soil surfactant and tons or organics in the area to "soften the soil". I can elaborate/provide links if you're interested.
I'm not sure Bella is worth the money, but it can't hurt. But regardless it sounds like the soil needs work..
