In the United States it is generally accepted that the correct form of address for a bishop or an archbishop is “Your Excellency.” This actually correct everywhere, but in some countries it is also correct–albeit perhaps less formal–to address them as “monsignor,” which means my Lord. In the US we typically only use monsignor to address priests who have been given one of the monsignorial titles (Chaplain of His Holiness, Prelate of Honor, Protonotary Apostolic). “Your Grace” and “Your Lordship” are not used in the US for Catholic bishops.
Cardinals may be addressed as “Your Eminence” or “Lord Cardinal” as per the most recent legal document on the matter, from Paul VI. The latter is less formal, but probably does not appear so.
As far as the bowing, genuflecting and kissing are concerned, it is certainly traditional to genuflect on the knee (usually left) and kiss a bishop’s ring. It is not required, and may be inappropriate in certain circumstances, but it is a traditional Catholic practice and there is nothing wrong with it in principle. People do it to the Pope all the time, and if you have a habit of watching episcopal liturgies on EWTN like liturgy nerds such as me, you see people kissing bishops’ rings all the time as well.
In sum, I would say:
Cardinal, “Your Eminence” or “Lord Cardinal”
Archbishop or bishop, “Your Excellency;” “Bishop” seems rather informal to me unless connected to his surname like “Bishop Johnson,” but is a term of direct address in use (by way of analogy, wouldn’t it seem weird to address the Sovereign Pontiff in person as Pope, as in, “Hello there, Pope!” I think so, rather awkward. Same situation here.)
Genuflecting and kissing may be done, but seems to me dependent on circumstances
