IMO I would pull the shrimp now, if you're worried about another cycle let it dot for a week and add a fresh piece of shrimp, let that cycle out remove and let the tank sit like that another week or so. Then you can add your cuc and macro. Again let it hang out a week or so after that. Then you should have a bullet proof cycle and be ready for a fish maybe 2. Then after that I wouldn't add more than one fish every 2 weeks. And remember peaceful fish first aggressive last. I did a similar cycle style and used Dr.Tim's one and only. I messed up and froze Tue cycle but when I got it going again it went very fast, and haven't had a problem since then. Good luck!
I wouldn't go out and by a full blown CUC for your tank for the reasons you stated, but you can go ahead and start with a small CUC along with the macro/pods. I'd add the macro/pods now that your ammonia/nitrite levels are at zero. I'd wait a few more days and add a small CUC (leave the shrimp in, the bacteria and CUC will take care of it). Then, I'd do a water change and add in your first (few) fish. If you have a QT, which I'd recommend, you can probably get the fish started in there now. Have you made a decision on stocking yet?
