If you idle hangs after WOT that normally means your HSN is too lean. If it drops to idle and then goes back up that means your LSN is too lean. If you have richened the HSN to stop the problem but now it wont change into second gear you need to adjust your transmission clutch. Tune your transmission around the engine not the other way around. And always tune the HSN first and THEN the LSN. Don't mess with the LSN until you have the HSN properly tuned. Sounds like you need to go back to base line needle settings and start over. Also you need to check and make sure you don't have any air leaks as that will cause similar symptoms. Your fuel tank cap may not be sealing properly or you may have a leak around your carb base.
