I don't think running a 7sp RD with 8sp Ergo shifters will work, but I do know that running 8sp Ergo shifters with 8sp RD & 7sp freewheel/cassette works just fine.
By the same token, the 8sp Ergo shifters should shift a 9sp RD over an 8sp cassette just fine.
Another option is to obtain the 9sp Ergo insert for your 8sp Ergo shifters, as well as the appropriate RD & cassette/freewheel. My brother switched all of his 8sp Ergo drivetrains to 9sp by switching the inserts & cassettes.
