We currently use two difference Resolutions, one Corporate and one Sole Prop. Do we also need seperate Resolutions for LLC, Partnerships and Associations/Organizations?

Normally yes, but you need to be visiting with legal counsel.

Is there a guide sheet for Corporate resolution's? We have questions on Corps that have dba'a and Corps that have Company's showing as the General Partner. We have one acct that shows 3 different enities that are involved under the main Corporation.

You might ask your document provider if they have some sort of guide on when to use which resolution. Generally, the only person with less of an idea than the new account rep about which resolution to use is the business owner.
