What templates, addon's, plugins work with CB 3.0?

I'm just starting to build out my 3.0 community site using the QuickStart Pro. A great package as it provides the core functionality plus many useful features all at once. QuickStart is the way to go! However, now I want to expand the features in a sanbox site I'm setting up (may add Incubator, advanced/pro, etc). But the list of additional addon's/plugins is impressive and I'm not sure which is appropriate for a 3.0 installation OR which ones will overwrite the QuickStart Pro 3.0 implementation. It would be very helpful to have some type of list indicating what to configurations work well (or somewhat or not at all) with 2.5/3.0 and QuickStart Pro. Do you have some guidelines to help point me in the right direction? Second question: Can I download all the incubator plugins/addons in one package, it looks like aside from the Action Pack they all need to be downloaded one at a time. Thanks

We don't have a CB 3.0; you mean CB 1.9? All of our products work with CB 1.9, can't help you with 3rd party extensions as we don't test them.

Yes, please see our package builder found below.
