Hi TJORDAN and welcome to the Q&A Board!
Do you have the right lens adapter for your camera? It should be if you bought one made specifically for your camera. Here's the one Kodak produces.
Kodak adapter >I suspect that the more items you add to the front of your lens, the more vingetting will occur. Have you tried zooming in the lens rather than use it at its widest angle? This can eliminate all or some of the vingetting.
I'm not sure you wasted your money on the filters and step up ring but I'm don't think the spacer rings will solve the problem.
